There are many.\n\nFirefighters use them to scan smoke filled rooms for victims.\n\nBiologists use them to track animals in the dark\n\nPolice use them to see 'through' walls and look in on bad guys.\n\nMeteorologists use them to look at weather systems\n\nAstronomers use them to look at distant planets and stars\n\nThey are used as a quality assurance tool in manufacturing. They can accurateky measure food temperature for pubic health in food establishments.\n\nThere are thousdands of end uses for an IR camera system.

That should work pretty well, since the CCDs in most cameras are sensitive out to about 950 nm.  This is only the very near infrared.  The above author I think meant to say to put a piece of exposed and developed film in front of the CCD. This will block out most visible light and let most of this near infrared through. You might have to step the frames/sec down if the camera does not automatically adjust its exposure.

A thermocouple can be a temperature sensor or it can be a means of converting heat energy to electricity. Many deep space probes use thermocouples (a series of thermocouples) powered by radioisotope decay for electricity production.

Depends of if the body temperature is the same as the surrounding, for example a snake that has been sunbathing for a few hours before dark will remain warmer than its surroundings for some time, so thermal immagery devices could have limited use. I'd say a flashlight or headlamp would probably be just as much use in most cases tough.

a thermistor is a resistor whose resistance changes with temperature. Because of the known dependence of resistance on temperature, the resistor can be used as a temperature sensor.\n\nSo, add a thermistor into a simple circuit with a power supply and a meter to measure current and you have the essence of a device to measure temperature.\n\nGet a bucket, fill it with ice and leave it till the ice has half melted. The temperatue of the water will be 0 degrees C. Pop in the thermistor (suitably electrically insulated) and measure the current.\n\nBoil a pan of water on the stove. As it's bubbling the water will be exactly 100 Degrees C, and again measure the current.\n\nUsing both values you can calibrate your new electronic thermometer!

I can think of two ways to measure the absorption and reflection coefficient of a material.  The first would only work with a polished surface.  First measure the intensity of a laser beam with a photodetector, then shoot the laser beam at the surface and aim the reflection at a photodetector.  Coefficient of reflection = transmitted intensity/initial intensity  (coefficient of absorption =1-reflection).  The other, harder way, which would work with any material, is to measure the heat gain in the target.\n\nFor this you're gonna want as small a piece of the target material you can get so that the laser still completely hits it.  Now attach a thermistor to the back of the target (again the smaller and thinner the target the better, ideal would be a foil just thick enough to be completely opaque).  Now shoot the laser at the target and measure the temperature as a function of time  It should be linear up until it starts radiating nearly as fast as it absorbs energy, so take points until it starts to level off and drop points after that.  Now find the specific heat of the thermistor-target apparatus by dipping it in water with a thermometer in it, using the initial and final temperature of the water, the volume of the water, and the initial temp of the apparatus, determine the heat it absorbed per degree it's temperature changed (this will actually give you specific heat*mass which is fine).  Now convert your temperature vs. time data to heat vs. time using the specific heat you determined (temp*(specific heat*mass)).  The slope of the line of best fit for this data will give you the rate it absorbed energy in watts.  Divide this by the lasers output in watts and you get the absorption coefficient.

There are several ways to do this:\n1. thermocouples\n2. thermionics\n3. thermophotovoltaics\netc\n4. thermal diodes

That just means the detector was most sensitive to infrared light.  It just depends on what material the detector was made of.

There are a few cameras that almost meet your requirements. Unfortunately, none of them have a battery option included, but they generally run off on DC which means the addition of a battery pack is possible.\n\nThe first link is not only low light but also infrared. The others tend to have a low light option.\n\nSee links in source(s):\n\n--\nsf

Half-lives are part of the answer.\n\nIt is also used to compute the amount of energy absorbed by an exposure to radiation of this or that energy, of a given intensity for a given period of time.\n\nIt is used to construct the tables that tell the X-Ray technologist how to set up the machine (kV and mAs) to take chest films, hand X-rays, and whatever else: that's called Technique Charts.\n\nCT and MRI scanners use mathematical algorithms to generate the pictures they take--usually a version of Fisher & Tukey's fast factoring algorithm for 2 or 3 D reverse Fourier transform...  Yeah, right, that's a mouthful, and I hope I've got it clearly...\n\nThey used to use it to figure out how to move the X-ray emitter and the film to do plain old tomography, but on the whole, that's gone by the wayside since the advent of computerized tomography (CT)\n\nThere's probably more, but that's a good start.

Here are some of the more common applications of these techniques:\n\nGas Chromatography - Flame Ionization Detector, also called GC-FID.  This method is used to analyze mixtures of substances which have an appreciable vapor pressure and are capable of burning.  GC-FID is often used to periodically check a reaction mixture to see how far a particular reaction has gone.  It is also used to check for purity of the final product and to check for undesirable impurities.  \n\nHPLC can also be used in a similar way to GC-FID except that it is better at analysis of non-volatile compounds.  HPLC is often used to analyze the final purity of a product, or to analyze the concentration of a pharaceutical product in a physiological sample (blood, plasma, urine, etc).  \n\nUV-vis is good at measuring the concentration of a UV-absorbing compound in a matrix which contains no other UV-absorbers.  Sometimes you can take your final product and dissolve in non-uv absorbing solvent and measure the UV-vis absorbance to determine concentration or assay.\n\nThe above are just some of the more common uses.  There are many more uses for these techniques in the Pharma industry.

It depends on the centre frequency and bandwidth of the IR detector.  Glass will absorb certain IR frequencies, very often IR detectors use this as they do not wish to see beyond windows which would cause false alarms.

In slightly more simple terms the major components are the IR source, laser, interferometer and detector.  Of course the computer to perform the transform is critical, but not usually considered part of the FTIR.

Many different ways.  Camera obscura.  High density filters.  Extremely fast exposures, etc.
