英文摘要	An avalanche photodiode array detector consists of a photosurface and a dead zone. The photosurface is the area where the photoelectric effect occurs, while the dead zone is useless to detection and reduces the light energy utilization of the detector. Generally, coupling a microlens array can solve this problem. However, when the detected target moves, a part of the light concentrated by the lens will deviate from the photosurface to the dead zone, which results in a loss of energy. We design a micro compound parabolic concentrator array to replace the traditional microlens array. Having a large acceptance angle, the compound parabolic concentrator can concentrate light beams with an incident angle smaller than the acceptance angle. Even if the incident light is deviated by a certain angle, most of the light can effectively be concentrated onto the photosurface as long as the deviation angle is smaller than the acceptance angle. Hence, it has higher light energy utilization than a microlens array. © 2019 Optical Society of America.
