摘要
分块式平面侦察成像系统(Segmented Planar Imaging Detector for Electro-optical Reconnaissance, SPIDER)是基于光子集成回路的干涉成像系统,是提高遥感成像分辨率,降低系统加工难度,减少系统体积、质量、功耗的有效手段之一。首先报告了SPIDER研究现状;并对其基本原理与组成进行了研究;建立了基于部分相干光理论的成像模型;研究了基于平衡正交检测的干涉条纹检测方法;分析了成像系统指标体系;最后对SPIDER成像能力进行了仿真验证。结果表明,SPIDER成像系统具有良好的成像效果,在遥感侦察、空间态势感知等领域具有良好应用潜力。
The Segmented Planar Imaging Detector for Electro-optical Reconnaissance(SPIDER) system is an interferometric imaging system based on photonic integrated circuits. It is one of the effective means to improve the resolution of remote sensing imaging, decrease the difficulty of system processing, and reduce the size, weight and power. The current research status of SPIDER is reported. The basic principle and composition was also studied. An imaging model was established based on partially coherent light theory. The method of interference fringe detection is studied based on balanced four quadrature detectors. The index system of imaging system was also analyzed.Finally, the SPIDER imaging capability was simulated and verified. Based on the results of simulation, the imaging ability of SPIDER can broaden its application in remote sensing reconnaissance, spatial situation awareness and other fields.
