Here you can see the D40x sensor with its IR blocking filter removed. Without this filter, and without an IR passing filter, the D40x now records both IR and Visible light.
Do you clean your own sensor? I bought the MARUMI Low Pass Filter Cleaning kit which I will attempt to use next time I have dust on the sensor. Getting tired of having the camera shop do it.
Lighting details: SB800 on camera bounced off ceiling. SB600 handheld pointed at a 1m diameter reflector on the floor angled to point to me. Triggered with Nikon CLS.
For those who've wondered at my probably annoyingly often references to the damage to my camera, here it is in all its glory.
The only reason I'm sharing this is because of the amazing flare my 10-20mm produced here.
SNL Dennis Roach with a Comparative Vacuum Monitoring (CVM) Sensor showing galleries etched-sensors underside. He lead team that's evaluating some-sensors for Structural Health Monitoring (SHM) aircraft and safety equipment.
The Comparative Vacuum Monitoring sensor is a self-adhesive rubber patch, ranging from dime-to credit-card-sized. The rubber's underside is laser-etched with rows of tiny interconnected channels or galleries to which an air pressure is applied. Any propagating crack in the materials under the sensor breaches the galleries and the resulting change in pressure in monitored. The sensors are made by Structure Monitoring Systems, Inc. (SMS) of Australia, are in expensive, reliable, durable, and easy to apply. They provide equal or better sensitivity than is achievable with conventional inspection methods. Besides, aircraft, SHM techniques could monitor the structural well-being of spacecraft, weapons, rail cars, bridges, oil recovery equipment, buildings, armored vehicles, ships, wind turbines, nuclear power plants, and fuel tanks in hydrogen vehicles.

La población de Keta se encuentra a la izquierda de la imagen, en la barra litoral (coastal bar) o brazo de tierra que separa la laguna de Keta (un humedal Ramsar) del Golfo de Guinea. Otras poblaciones sobre la misma barra son Tegbi, Woe y Anloga, esta última en la parte más meridional de la barra. A la izquierda de la imagen se ve discurrir el río Volta hasta su desembocadura, donde encontramos la ciudad de Ada Foah.
En la visualización SWIR (infrarrojo de onda corta) la vegetación aparece en tonos claros de verde mientras que el suelo desnudo y las zonas urbanizadas lo hacen en tonos de color marrón claro.
Short wave infrared (SWIR) measurements can help scientists estimate how much water is present in plants and soil, as water absorbs SWIR wavelengths. Short wave infrared bands are also useful for distinguishing between cloud types (water clouds versus ice clouds), snow and ice, all of which appear white in visible light. In this composite vegetation appears in shades of green, soils and built-up areas are in various shades of brown, and water appears black. (EO Browser)

New safety installation at the industrial railway of Stadler when crossing the main road. This system operates independently of the normal train protection. If a shunting loco stands above this sensor, the system can be activated by a smartphone app. Staad, Altenrhein, Switzerland, March 7, 2015.
LSST Mechanical Engineer Travis Lange is seen here. The Legacy Survey of Space and Time (LSST) camera team installs the four corner RTMs and the first science RTM into the camera cryostat. The focal plane holds 21 science rafts -- 3-by-3 arrays of state-of-the-art imaging sensors. Together they'll take unprecedented 3,200-megapixel images of the night sky, which, over time, will produce the world's largest astrophysical movie.

JPGs straight out of camera using Nikon's NATURAL colour profile. The old CCD sensors have been said to be more filmic (if not noisier) and this is the Nikon D60, and Old DSLR which was first announced back in Jan 2008 (a 15 year old camera)
In many fatigue assessments characterising the applied service loading is the most difficult and critical step.
Fatigue Integrity Management has over fifty years experience in the design and installation of systems to allow in-service load or stress spectra to be established through acquisition and analysis of load, strain and displacement records.
CrackFirstTM sensors provide an alternative long term system for fatigue usage monitoring on steel structures. Attached adjacent to a fatigue critical detail, the sensor responds to cyclic loading by changing its output in proportion to the cumulative fatigue damage for a typical fillet welded joint. The sensors allow an estimation of remaining life of the structure and safe usage-based inspection intervals.
A wide range of structures and components has been assessed for TWI Members including earth moving equipment, road trucks and tankers, bridges and pressure vessels.
TWI operates a quality assurance scheme certified to ISO 9001:2000 by LRQA and BS EN ISO 14001:2004
and is an IiP certified company.

Los domos de sal y glaciares salinos son una característica común de la cordillera de Zagros. Los domos de sal son un estadio de los diapiros salinos. Los diapiros son una estructura importante para la exploración de petróleo, ya que la sal impermeable atrapa con frecuencia el petróleo debajo de las capas de rocas. (Wikipedia). Bushehr (223.000 h) se encuentra en la esquina superior izquierda de la imagen.

A view through the germanium(?) lid of the Therm-App sensor.
The sensor is a Ulis Pico384 384 x 288 pixel amorphous silicon microbolometer device. The pixels are, I believe, 17µm and thus a bit too small to see here! To give you a sense of scale, the large dark rectangle in the middle (the microbolometer array) is about 6.5mm wide.
Normally you can't see any of this detail because it is protected behind a thin, optically flat sheet of germanium (or silicon, I'm not certain which) that does not allow visible light through. There are probably also coatings on the sheet that further limit the transmission. The only practical way to see through it is by using a thermal imaging camera, which is what I did here.
This image was made with another Therm-App using a 13mm lens adjusted for closest-possible focus. As you might expect, there is very little actual thermal contrast when looking at a thermal sensor (or there'd be image hotspots everywhere!) so the Therm-App struggled to get a picture out of the noise. But there are ways to overcome that hurdle, at least to a certain extent, for stationary objects - and to get better resolution at the same time.
A lot of exposures were made (>200) and the best 100 or so were then stacked in Registax 6. This provided a significant increase in definition thanks to its superresolution techniques, and a very considerable reduction in image noise.
I hope to make another, similar image with a more powerful lens one day. By doing so I'd have to image the sensor in sections, process each section in the same way as this image, and then stitch the images together. It's likely to take a long time, starting with probably a thousand or more source images. But with any luck the results will be worthwhile.
Comments, as always, are very welcome.
I went to Derby (to pick up a silicone blower to remove some sensor dust) the day after the riots in the Midlands and I met Zita.
She was very obliging and willing to be photographed for the project which I really appreciated. Her mood was very friendly and accommodating which was in contrast to the slightly unnerving feeling the city had that morning.
Zita is 21 and works at a hotel in the city. I was having an off day and it took me a few shots to get one I was reasonably happy with, I also wanted to go mono as I haven't had a mono image for a while in my portfolio.
Zita - thanks for the time and I hope you like the portrait.
This is shot 51 in my 100 Strangers Project.
