Working Principles
An IR Detector Diode operates based on the photoelectric effect. When infrared radiation falls on the diode, it generates an electric current. The diode consists of a semiconductor material, typically made of gallium arsenide (GaAs) or indium antimonide (InSb), which has specific properties that enable it to detect infrared radiation effectively. When the infrared photons strike the semiconductor material, they transfer their energy to the electrons, causing them to move and create a current. This current is then amplified and processed to obtain the desired output signal.
