Abstract

Low background noise is a necessary condition for infrared optical system to achieve long distance and weak target. The noise of long-range weak target detection system is mainly determined by the thermal radiation of the optical. Cooling optical components is the most direct way to obatain low noise. The article describes a light and compact integrated cryogenic optical system, cryogenic optics detector, which is different from the traditional cryogenic telescope module. In this model, imaging lens is assembled in an infrared detector, then the imaging lens is working at temperature low 100K. So a new detection model that realizes ultra-long-distance and ultra-high sensitivity detection at the expense of very small volume power consumption is proposed. The prototype test results show that the integrated cryogenic optical system has good imaging results, and the thermal energy received by the FPA has been greatly suppressed.
