Laser imaging guidance is one of the development directions of precision guidance. A laser imaging guidance detector is the key component for a laser imaging system. The research progress of laser imaging guidance detectors including HgCdTe focal plane arrays, Si Avalanche Photodiode (APD) focal plane arrays and InGaAs PIN detector and APD focal plane arrays are presented. Among them, the InGaAs APD focal plane arrays will become the main development direction for laser imaging guidance detectors. Their key technologies include growth of epitaxial materials, fabrication of high uniformity detectors and design of readout circuits.
