The major applications of solar thermal energy at present are heating swimming pools, heating water for domestic use, and space heating of buildings. For these purposes, the general practice is to use flat-plate solar energy or evacuated tube collectors with a fixed orientation (position).\n\nThe highest efficiency with a fixed flat-plate collector or evacuated tube collector is obtained if it faces toward the equator and slopes at an angle to the horizon equal to the latitude plus about 10 degrees. Solar collectors fall into two general categories: nonconcentrating and concentrating.\n\nIn the nonconcentrating type, the collector area (i.e. the area that intercepts the solar radiation) is the same as the absorber area (i.e., the area absorbing the radiation).

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.

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.

Radiation caused by temperature is often called "Black-Body Radiation." Perfectly Black Bodies are the best type of objects to absrob heat - as most of us know if you wear a black T-Shirt in the sun, as compared to a white one!\n\nI quote to you a fundamental statement of black-body radiation "The best possible absorber of radiation is also the best possible emitter of radiation."\nThis is because the efficiency of a black body does not depend on whether radiation is being emitted or absorbed.\n\nA black radiator is much more efficient than a white radiator because it can absorb (and therefore radiate) better.

many materials absorb better at the infrared wavelengths than the shorter wavelengths so the absorbed energy is conserved as heat.  There are materials that absorb shorter wavelengths and convert the energy to heat, such as a microwave oven???  Water absorbs at that frequency (1-2 GHz) and the water molecule resonates.  The vibrational energy is re-emitted as heat due to a Stokes shift.\n\nThe shorter wavelengths are more energetic and more capable of depositing energy that might show up as heat but it depends on the absorption of the material itself.

The theory of the pneumatic pyrometer, in which gas temperature is determined from density measurements, is outlined and the design and characteristics of a small instrument are reported. Calibration curves covering a wide temperature range (200 to 1550° C) are given and the use of the instrument is described. :-)

the main type of radiation produced is visible and infrared radiation but all types of radiation is produced in various amounts.

Any object having a temperature above absolute zero will emit electromagnetic radiation.  The frequency distribution of the emitted radiation is determined by the temperature of the body.
