Thermal imaging cameras are typically used to identify faulty equipment, although they were also used in the pandemic to identify feverish humans (with limited success). It's a relief to see that I'm apparently in rude health here.
Taken with a FLIR E60 thermal camera, with no delay timer or remote, so I used a metre stick and poked the trigger from an appropriate distance.
In post-processing, I've tried my best to undo some of the evil effects of the heavy JPEG compression by denoising the image. I've also cropped slightly to help with framing.
My smallest Flickr post by some distance; just 267 by 200 pixels.
This is a thermal image of a home in the northside neighborhood of Cincinnati, Ohio in the dead of winter. You can see the windows glowing red indicating there is tremendous heat loss.

This is the first thermal image of Barred Owls that we have shared.
We are using a thermal imaging monocular for this purpose.
The Owls look a little spooky, but sometimes an Owl can be very hard to locate in the forest canopy.
The thermal imager that we are using to find Owls is pretty cool, but its resolution is kinda low. Nor does the device have any auto-stabilizer built in (so my views of them can be very shaky), but the imager does allow us to save even shaky videos of what we are viewing.
Our work with thermal images to find wildlife is in its infancy, but it does provide a nice tool in our utility belt.
Once we have a video, we take snapshots of interesting frames and that is what we are sharing here.
Something a little different. A herring gull (_Larus argentatus_) paddling for worms in Southampton taken as a thermal video. It is thought that the paddling vibrations trick worms into surfacing, thinking it's raining.
From cold to boiling time-lapse.
Shot on the FLIR One, uploaded SOC. Shot at two second intervals.
Something a little bit different, a result of a drizzle filled Saturday morning.

Test video of a Therm-App thermal imager recorded at 720p via a Nexus 10 tablet.
I used the HDMI output of the Nexus 10 to feed a video digitiser at 720p. (The system also works at 1080p but I chose 720p because it's nearer one-half the native resolution of the Nexus 10's screen).
The video is nothing special - my back garden - but I think it shows the Therm-App (with ThermAppPlus) working surprisingly well. It's an interesting thought that the resolution of a Therm-App thermal camera is on a par with many old VHS camcorders...

I'm playing around with a cheap USB charger as a test target for X-Ray imaging. When I actually used the charger for its intended purpose I noticed it got rather warm to the touch, so I thought I'd try taking a thermal image and combining that with an X-Ray picture. I think the result is quite pretty!
So, this image is made by employing wavelengths ranging from 14µm to 30pm.
The X-Ray was made with a heavily modified Scanmax 20 mailroom X-Ray scanner. The thermal image, obtained when the charger had been on for about an hour, was made with a Therm-App thermal imager using ThermApp Plus software. The images were combined in PaintShop Pro.
Comments are warmly welcomed.

The fire hose water is made from Lego Clickit plastic necklace strings with studs at each end that clicked into the blasters and the underside of bricks behind the house.
Thermal image of Weymouth Harbour, taken from the lifting bridge.
Image made with Therm-App thermal imager, ThermApp Plus driver software, Microsoft Image Composite Editor and Paint Shop Pro.
Thermal camera image of what looks at first glance to be some kind of studio control room. It's actually a large ham radio shack - GB3RS - at the RSGB National Radio Centre in Bletchley Park, UK. If you visit you can learn a lot about radio in general and see the ham radio station in action, communicating with people around the world.
This is an ordinary wall-mounted electric convection heater as seen by a ThermApp Pro thermal camera. The image has been manipulated to change the colour palette but apart from that is essentially what came out of the camera.
It's amazing how something as mundane as an electric heater can spring to such vivid life when looked at in a different spectrum from what our eyes perceive.
This image was originally made to demonstrate a technical point about moiré patterns but I thought it looked colourful and interesting enough to show here.
ThermApp Pro 640x480 thermal camera with 35mm lens, ThermViewer driver software with superresolution to 1280x960, Corel Paint Shop Pro X for colour manipulation.
Stitched thermal panorama of Gibraltar and its harbour, with a little of the Spanish coastline visible at the very top.
Taken from the cable car station atop the Rock, looking more or less west. The pylon on the extreme right is the last support for the cable car.
This image was made with multiple shots from a Therm-App Pro thermal camera using a f/1.1 35mm germanium lens, ThermViewer driver software, stitched in Microsoft Image Composite Editor and given final tweaks in Paint Shop Pro.
At 6421x2886 (18.5Mpix) it's one of the largest, highest resolution thermal images I've ever made. You can download the full resolution original to explore all its detail.
View of a small cottage in thermal imaging showing a mixture of effects - heat loss and some thermal gain from weak sunlight. The majority of the house is shielded form the sun by tall trees.
Image made using Therm-App thermal imager and Microsoft Image Composite Editor.
One of my problems with attempting hyperspectral imaging has always been making sure that the alignment between the different images is at least reasonable. Here I have mounted a Therm-App thermal imager on the hot shoe of a Nikon D3100 DSLR. This gives a predictable and repeatable relationship between the two images, although there are still parallax errors (particularly for close items).
In this staged shot the thermal image on the phone screen was taken a few moments earlier and the rig repositioned so that the live view on the camera screen looked right. The parallax error at this close range was very significant.
This setup opens the door to putting several bodies together (a pair of IS PROs for UV and NIR, the D3100 for visible and the Therm-App for LWIR), giving coverage in one image from 14µm up to ~350nm, albeit with a MWIR gap from ~7-1.2µm. (I'll keep my eyes open on eBay for an ad MWIR camera...)
Of the two glasses of water, the one on the left was straight from the cold tap and the one in the right had had a dash of warm water added so that it was a little over lukewarm. The difference is clear in the thermal image but of course indistinguishable in the visible image.
The 6.8mm Therm-App lens was found to have a field of view approximately equivalent to a 28mm lens on a 35mm full frame. It does however exhibit quite strong optical distortions, which will have to be compensated for before thermal images can be overlaid on a visible or other image. (This assumes that the visible camera's lens is distortion-free – a big assumption...).

This is a close-up of a Raspberry Pi 3 processor 'thinking'. Various parts of the silicon chip heat up as they are used for different processes.
This movie was shot in real time whilst running a benchmark to test different parts of the processor. It was filmed using a Therm-App thermal imaging camera with a 13mm f/1 germanium lens, with ThermAppPlus driver software.
The granularity of activity on the processor chip isn't as fine as I'd have expected. You can see from the writing on the IC package that the focus was pretty good, so nothing is getting blurred by any settings of the thermal camera. I guess there's some sort of heat spreading going on inside the package, either just through the silicon itself or perhaps it's on some sort of conductive substrate. (Whatever it is, it's not very thick - the chip package is very slender and, as you can see from the X-Ray image referenced in the comment below, doesn't seem to contain anything particularly X-Ray opaque, like copper).
I was disappointed by the way the temperature display figures came out on the video. But they're just about legible. One day I may re-shoot this using a different recording method so the figures show up better.
The temperature range between the coldest and hottest parts of the chip is about 15°C, so it's not getting particularly stressed. I imagine it would get a bit hotter running really processor- and graphics-intensive stuff. However, it probably wouldn't show up so dramatically: you'd just get one big hotspot.

The main pyramids at Giza, Egypt, seen in thermal infrared and visible. Note that the two images were made from slightly different positions.
The thermal image was made using a Therm-App thermal imager with ThermAppPlus software to provide a mosaic image which was stitched together using Microsoft Image Composite Editor.

Even with an uncooled long wave infrared detector like the Therm-App it is possible to detect and see the small variation in temperature caused by the blood running just underneath the skin.

ThermAppPlus is simply awesome with a Therm-App thermal imager.
This is a simple LED lamp (in my bedside light) viewed with a Therm-App thermal camera and captured using ThermAppPlus, Rainbow mode, with Black Edges focus aid active. Post-processing (of a ridiculous 30 images) by Autostakkert! and final tweaks by Paint Shop Pro.
Thermal image of a domestic absorption refrigerator. Image made with a Therm-App Pro 640 x 480 thermal camera, ThermViewer software. Stitched from several images in Microsoft Image Composite Editor.
Uncalibrated image; blue indicates relatively cold (~room temperature); red is hottest (in this instance 'very hot to the touch of one's hand but not quite burning'). Image intended to show the general distribution of temperatures in the working sections of the refrigerator.

A colleague was kind enough to lend me a hand - literally - for thermography purposes.
Therm-App Pro camera, 13mm f/1.0 lens, ThermViewer software with superresolution enhancement from 640x480 to 1280x960.
This is a 300mm focal length LWIR reflector lens I recently acquired. Its primary reflector is about 270mm diameter and it absolutely DWARFS the Therm-App Pro with 35mm lens.
I’m having some teething troubles getting it to ‘talk’ to my Therm-App, which is not surprising given that it was designed to work with something quite different. But I have managed to get some kind of image out of it (a hand filling the screen at about 10m). I calculate that it’s probably the equivalent of a 1700mm focal length on a 35mm camera – very, very long!
Hopefully I’ll get to the bottom of this before too long. I’ll post updates as and when.
Sometimes, fortune smiles.
Making our way on a 400 mile journey down the motorway, the car computer beeped and said it had detected severe congestion ahead. We accepted its suggested diversion and ended up driving past a park where a hot air balloon was preparing to lift off. There was easy access and good parking so I stopped, pulled out my Therm-App thermal imager and fulfilled one of my ambitions - getting some close-up images of a hot air balloon!
Lift-off was imminent so there wasn't time for any finesse (or to take any video) but the place I happened to park was pretty well perfect, with an unobstructed view at just the right distance for the Therm-App 13mm f/1.0 germanium lens to work at its frame-filling best.
There wasn't even time to get out a stills camera. Just three minutes and thirteen seconds elapsed between me getting out of the car and the last take-off shot. In that time I took 56 thermal images, swapping palettes and adjusting temperature settings at breakneck speed. I'm glad ThermAppPlus is so easy to use!
The small visible-light image was actually taken from my car dashcam, hence the poor quality. The thermal images were taken from the other side of the balloon. Perhaps you can just see the white blobs of parked cars in the visible image - that's where I parked, too.
This was one diversion that brought a truly unexpected bonus.

- Water temp seeps through porcelain tank (radiates cold, absorbs heat ... whatever!)
- Seat isn't freezing cold, who-hoo!
- One application of thermal imaging is finding fluid (and sludge) levels inside tanks without having to look inside
This is a hand-stitched panorama comprising eleven Therm-App thermal imager shots taken in pitch darkness in Night Vision mode at St Paul's Bay, Malta.
Elsewhere on my Photostream you can see a photo of the phone used to take these images, set up so that you can see just how dark it was. There was street lighting, but that did not cover the bay, the boats, the buildings or the sky. The clouds, for example, were completely invisible to the naked eye.
This just goes to show that what they say about thermal imaging - light is irrelevant - is absolutely true.
Image made with Therm-App themal imager, 19mm lens, Nexus 5 phone, small tripod. Actual overall image resolution estimated at 400x1500 pixels, which was upsampled a bit in the phone using the standard software. The stitching was done in an old copy of Paint Shop Pro, and I also did a bit of contrast enhancement using the Curves tool and applied a bit of sharpening for good measure. I didn't attempt to be subtle with the stitching. Correcting images, stitching, cloning and so on is part of my day job and I have the touch to do it well when I need to - and someone else is paying!
I deliberately left all the 'footer' bits in the image so you can see how it was put together, but it looked awful when I had all the Therm-App logos on the top so I'removed all but one of them.

Four thermal images of the Fujifilm IS PRO made using a Therm-App thermal imager with 19mm germanium lens.
The IS PRO had a Domiplan 50mm f2.8 with a lens hood and Baader U (Venus) filter taped to it - not that affects the thermal image in any way...
Apologies to Andy Warhol.
This is, of course, a composite shot of four images. Each was made separately, using one of four different palettes built into the Therm-App software. IMHO the monochrome image gives the best spatial resolution, as is usually the case. The next best, I reckon, is the Iron palette, top left, but these don't have the visual impact of the other two.
I'm actually quite impressed that the 19mm lens on the Therm-App managed just the right depth of field to capture the camera and lens in pretty good focus and throw the background into a fairly flat bokeh. Now there's a thing - considering the bokeh of a thermal image...
