A LiDAR Photodetector is a light sensor used in LiDAR receivers to detect returned laser pulses and convert them into electrical signals for distance and reflectivity calculations. Photodetectors may be photodiodes or APDs depending on required sensitivity, range, and background light conditions. Key parameters include bandwidth, noise, responsivity at the laser wavelength, timing response, and saturation behavior. LiDAR detectors are used in mapping, navigation, and industrial measurement. GPD Optoelectronics manufactures photodetectors for LiDAR applications.
Learn where near-infrared photodiodes fly in aerospace systems, which specs deserve a hard look, and why in-house fabrication, military-standard testing, and lot-level traceability matter for missions that must work the first time.
