An MCA Cat III Workboat, owned by Aspect Land & Hydrographic Surveys Ltd, of Ayrshire.
The 'Marine Sensor' is road towable, and with a small forward cabin, can deploy from a slipway or boat hoist / crane and able to operate a wide variety of sensors.
Her hulls and catamaran configuration lend a fast transit speed and give good directional stability resulting in high quality survey data.

Fujifilm XE-1 with 18-55mm zoom in downtown DC. I can't get enough of these old houses in the District. The fuji 18-55mm zoom is as sharp, contrasty and free of distortion as any Leica, Voigtlander or Zeiss prime lens that I've ever used and the X-Trans sensor in this camera is magic. I kept the Velvia jpegs for most of these shots but found the raw files more useful in extreme situations. Once again, 80% or so of the jpegs were good enough and it wasn't worth fiddling with the RAW files unless I needed to pull detail from extreme high contrast shadow areas.
Optically Stimulated Luminescence-based radiation detectors developed by researchers at Pacific Northwest National Laboratory, can be used to detect special nuclear materials being smuggled into the country via sea containers. Also known as smart sensors, these battery-operated detectors are strategically located inside sea containers and information is collected via wireless personal digital assistants.

The precipitation sensor was installed about 5 feet above the surface on the piling in the foreground, with power connected through a nearby Climate Reference Network box (background).

My CCD sensor before cleaning. Dust and stains all over! It was even dirtier before this shot, these are the stains that I wasn't able to remove with air.
To see how dirty your sensor is, focus to infinity, set aperture to smallest setting and point your camera at a light even source, eg. a white computer monitor.
Before and after pics from cleaning my D600 sensor for the first time.
I used Sensor Swab Type 3 and the Eclipse Optic Cleaning Fluid, both bought from Amazon.com

It took 4 swabs to get it 99% clean (3 would have been fine, but I was being OCD about 1 tiny spec). Here is the before and after in full resolution!
Shot with the Tokina 17-35, F14, ISO 800, 1/4s for all shots, around 17-19mm. AWB made the last photo a bit different colored, but you get the point :)
Total end cost to me was about $47, which is less than a typical shop sensor cleaning, and I still have 8 swabs left -- good for another 2 or 3 cleans hopefully!
Corner test! 100% crop version.
Corners are always less sharp. The chip density is on the limit. Sensor is slightly oblique in this picture.
Test object : KC73129MP
Number of Effective Pixels: 500(H) ´ 582(V)
Unit Pixel Size: 9.80um(H) ´ 6.30um(V)
This is a CCD with fine structure as a test object. The structure is uniform, perfectly straight and the dimensions are fixed. The macro magnification can be measured easily.
Here you see that the Mit 2X lens sits on the edge of its capabilities. This lens has 5 microns resolution and that is very close to the pixel density of the measured sensor. Still, I find the results pretty well. All measurements are made with the same tube lens. At this 2X version there is an adjustment done for chroma abravation correction.
Note:
There's a window right on the chip. This can have negative impact on the resolution. I can not remove this window.

As a precautionary measure to COVID-19, these pedestrian buttons have a 'touch-free' sensor which registers a pedestrian's call without physical contact. The light ring blinks green when a person's hand comes close enough to the sensor.

Research at Baskett Wildlife Research and Education Center is looking at the effect of climate change on Missouri forests. Sensors scattered throughout the forest monitor carbon sequestriation and moisture moving through the soils and roots. Each half hour the sensor uses lasers to analyze what is going on below the surface.

Fun fact: the orange light on the right is inspired by a similar device attached to some types of city maintenance machines.

My prototype temperature sensor at work in my office, while my $6.00 cast iron chicken looks on. This board automatically posts the temperature to a mySQL database, and its associated webpage displays the temperature over time. Story of what it does is at... http://www.ka1kjz.com/861/temperature-webpage-update/
This is a picture I created for the tfttf 48 hour challenge. Image sensors shot on glass and illuminated from above and below. These are CMOS sensors made by Omnivision.
Pasó de un día a otro, seguramente por cambiar el objetivo donde no debía... Ahora estoy intentando dejarlo lo más limpio posible, pero no es fácil.
Test shots, fully stopped down lens on white paper, before and after cleaning the Sony α 77 ii sensor.

1. Blower.
2. Two passes with dry brush.
3. Two swabs dampened with cleaning fluid (4 passes).

It was a clear day and I had meant to do a dust/oil sensor check anyway, so f/16 + focus to infinity + point at the sky and here we are. Shutter actuation count is 3,585 so I'm above the anecdotal 3,000 shutter releases when the dust/oil problem is supposed to go away or be reduced.
There is visibly more dust on the sensor now than there was on the last check, although it's still not bad and mostly in the upper-left corner. I have been swapping lenses quite a bit lately, too. I might try to do a sensor clean soon.
IR sensor voor Fischertechnik kogelbaan. Ook een nieuwe extra curve 180° is bijgevoegd. De IR sensor kan werken op 5V en op 9V. Hij is niet gevoeilig voor omgevings licht. Zelfs getest in volle zon blijft hij correct werken. Het stroomverbruik dooe de IR diode is ongeveer 9mA en de load voor de Phototransistor is 5 mA. Burst van kogels worden mooi verwerkt.

Second check at image 1,617, after all the photos taken on a 10-day trip (with multiple lens changes along the way). Sometimes, I'll see something that looks like a hair on some of my photos and I'll have to see what thats about. Otherwise, there's still a little bit of dust on the sensor, but it's moved from the last check photo I took.
