Abstract

In order to study the formation and evolution of the universe, galaxies and stars, it is necessary to carry out high sensitivity and high resolution infrared astronomical observation on targets with low temperature such as infrared galaxies. In this paper, an astronomical telescope is selected to carry out quantitative observation experiment of infrared star radiation. Through a telescope focal platform deployment cold resistant infrared detector, optical design of long wave refrigeration cold optical design can effectively restrain the telescope infrared imaging terminal itself the effects of thermal radiation detecting background is extremely low, at the same time add infrared imaging lens, telescope optical path with infrared detector component, the telescope has the capability of long wave infrared observations. The infrared star radiation quantitative observation system is mainly composed of infrared optical imager, optical cold chamber design, infrared imaging movement, optical fiber data conversion device, display control system, calibration system, ground tools and so on. The system has data acquisition function, environmental monitoring function, temperature and humidity control function, remote terminal equipment display control management, calibration ability, self-check, condition monitoring function, etc., which can provide a technical basis for the subsequent quantitative intelligent measurement of infrared stellar radiation.
