Thermal Imaging camera

Could someone explain to me how exactly a Flir b365 or any similar camera works? You can also include some history but mainly just explain how they work with defintitions. Thanks.

Thermal Cameras basically work by intercepting the infrared energy radiated by the objects they are pointing at.

While they may look like a standard camera, they do not work in the same way. They focus the infrared energy onto a detector, this can be either a photon detector or a thermal detector. Most cameras used today use thermal detectors, specifically a microbolometer. With this type of detector, the incoming infrared energy will heat up the pixels, as they heat up their electrical resistance changes. System electronics and signal processing are used to produce an image. The image is not a picture of temperature, but instead is a picture of the infrared radiation intensity (thermal radiated energy), this is a combination of emitted, reflected and in some cases transmitted energy. Most cameras are calibrated for temperature, but the temperature value are subject to the thermogapher setting the user inputs correctly. A skilled thermographer will be able to interpret the images correctly and set the user inputs to give accurate results.

Also despite what has been posted elsewhere on these boards, it is not possible to turn a standard digital camera into a thermal imager. It is only possible to add infrared filtering to a digital camera and this does not take you far enough into the infrared region to image heat, so it is not thermal imaging.

There is so much history to this that it would take too long to type it out.

Not been smart but of you type it into Google and put wiki after what your looking for it should have a good bit of info
