A thermal camera, also known as an infrared camera, is an imaging device that captures the infrared radiation emitted by objects and converts it into a visible image. The camera detects the differences in temperature between objects and displays it as a color image, where warmer objects appear as red, orange, or yellow, and cooler objects appear as blue or green.
Theory:
Thermal cameras work by detecting the infrared radiation emitted by objects, which is a type of electromagnetic radiation that is invisible to the human eye. The camera has an infrared sensor that detects the radiation and converts it into an electrical signal. The signal is then processed by a computer, which assigns different colors to different temperature ranges and creates a visible image that can be viewed on a screen.
