English Abstract

A long-wave infrared optical system to detect the refrigeration type CCD for airborne despun device was de-signed.The re-imaging configuration was used to meet cold shield efficiency requirement,and optical passive ather-malization principle was applied to achieve athermalization compensation with a wide range of temperature.The aberra-tions are corrected by the aspherical-diffraction element,and the effect of diffraction element shape error on the optical system is discussed.The design results show that this system has compact structure and light weight.It realizes the athermalization compensation in the temperature range of -40~60℃.100%cold aperture efficiency and the control-ling cold reflection are also achieved.
