空间光学系统中红外杂散辐射的抑制方法
Suppressing Method of Infrared Stray Radiation in Space Optical System
摘要
根据红外系统中的不同杂散辐射源，分析了杂散辐射的内因和外因。列举了从机械面和光学面上抑制红外杂散辐射的具 体措施，提出了选择红外涂层的方法。对一台空间红外仪器设置了里奥光阑，并通过地面试验和在轨测试评价了其抑制红外杂散辐射的有效性。
Abstract
The causes of the stray radiation in an infrared optical system are analyzed according to different stray radiation sources. Some particular samples for restraining the stray radiation from mechanical and optical parts are listed. A method for choosing infrared coating is proposed. A Lyot stop is set up in a space infrared instrument and its suppression effectiveness for infrared stray radiation is evaluated in ground and in-orbit tests.
