Abstract

The Segmented Planar Imaging Detector for Electro-Optical Reconnaissance (SPIDER) imaging system combines synthetic aperture technology and Photonic Integrated Circuit (PIC) technology, which can reduce the size, mass and power consumption of traditional telescopes by one to two orders of magnitude. Simultaneously, it provides an effective way for future astronomical telescopes to have both large field of view, high resolution and light weight. In order to solve the problem of unsatisfactory image restoration effect of SPIDER imaging system, this paper proposes an optimized design based on a layered multi-level odd-even arm microlens array and an image reconstruction technology based on the clean algorithm. The simulation results show that the clean reconstruction algorithm based on the odd-even arm SPIDER system proposed in this paper can increase the peak signal-to-noise ratio (PSNR) by about 39% and the structural similarity (SSIM) by about 63%, which can effectively remove the artifacts caused by the system frequency truncation.
