摘要：
The Segmented Planar Imaging Detector for Electro-optical Reconnaissance system obtains target information through microlens and photon integrated circuit, which has the characteristics of small size, light weight and low power consumption, and is one of the research directions of high-resolution remote sensing in the future. This paper analyzes the influence of different waveguide offsets on the coupling efficiency of the system. The maximum coupling efficiency is 0.8145 without waveguide offset, and decreases rapidly with the increase of the offset. Finally, the calculation method of the optimal F number of microlens array is given.
