摘　　要：随着空间光学技术的快速发展以及光电探测器件性能的不断提升,高分辨率、多光谱、低探测阈值的遥感系统在航空、航天等领域的应用越来越广泛,对光电载荷的杂光抑制能力与评价指标逐渐严苛,杂散光抑制技术和仿真分析已成为不可缺少的环节之一。尽管杂散光的抑制与评估技术开展较早,但仍然需要系统性方法体系引领该技术的发展,以改变当前分散化、碎片化的研究现状。因此,需要建立一体化的杂散光抑制与评估方法体系,在杂散光抑制方案制订、抑制模型表面特性测量与建模、杂散光抑制效果仿真、杂散光测试及评估等四个关键技术模块进行深入研究。本文给出了一套整体技术路线,为更好推进杂散光抑制与评估技术的发展和应用提供思路。With the rapid development of space optical technology and the continuous improvement of the performance of photoelectric detection devices, remote sensing systems with high resolution,multispectral,and low detection threshold are more and more widely used in aviation,aerospace and other fields. And the capabilities and evaluation indicators for the stray light suppression of electric-optic load are gradually becoming stricter. The stray light suppression technology and simulation analysis has become one of the indispensable links. Although the domestic stray light suppression and evaluation technology have developed earlier,a systematic method is still needed to lead the development of this technology to change the current research status of decentralization and fragmentation. Therefore,it is necessary to establish an integrated stray light suppression and evaluation method system,and conduct in-depth research in four key technical modules,including the formulation of stray light suppression scheme,suppression model surface characteristic measurement and modeling,stray light suppression effect simulation,and stray light test and evaluation and so on. Based on the theory of stray light radiation transfer,we give the corresponding suppression methods according to the stray light inside and outside the field of view,and the internal thermal radiation stray light. But the actual stray light sources are complex and in various forms,often requiring various suppression methods together,such as selecting the configuration of the optical system,setting the baffle and vanes,adding the stops,coating the optical surface,and blackening the surface of the structural parts. In addition,in some specific cases,filtering method,adjacent frame subtraction method,polarization method,numerical aperture method,and image correction method can also be used to suppress stray light. Opto-mechanical systems are generally composed of various surfaces with different materials and properties and they have different characteristics such as re
