| Abstract: | In order to resolve high precision image plane scanning problem for cryogenic optical system of space infrared camera,the cryogenic scanning technology based on piezoelectric bimorph actuator has been studied.The radiant characteristic of cryogenic optical system has been analyzed.Based on the motional property,a matched scanner has been designed and fabricated,and the scanning properties have been tested at cryogenic temperature.The results indicate that the piezoelectric bimorph scanner can reach a scanning range of 2.4° and a scanning precision of 80 μrad,which meet the demand of cryogenic optical system of low-orbit space infrared camera. |
