Indium gallium arsenide (InGaAs) sensors are supplied by PAM-XIAMEN, a InGaAs sensor manufacturer. Its working principle is actually the principle of shortwave infrared (SWIR). And the working principle of SWIR-based sensor is similar to that of CMOS-based sensor, converting photons into electrons. SWIR technology [...]
