甚高分辨率扫描辐射计(VHRSR)是我国风云一号气象卫星上的可见红外多波段遥感仪器,是我国继红外地平仪之后,进入空间应用的又一红外仪器,标志着红外技术在空间应用上达到一个新的台阶。为了获取高质量的卫星昼夜云图,并能适应发射时的力学环境和入轨后的空间环境,研制时对扫描辐射计提出了一系列高的要求。为此发展了高性能的硅光电二极管、工作温度105K的碲镉汞红外探测器和辐射致冷器、超高真空下长寿命的扫描驱动器、
Very high resolution scanning radiometer (VHRSR) is a visible infrared multi-band remote sensing instrument on China’s Fengyun meteorological satellite. It is another infrared instrument that enters the space application after China’s infrared gradiometer. It marks the application of infrared technology in space To reach a new level. In order to obtain high-quality satellite day and night cloud maps, and can adapt to launch of the mechanical environment and after entering the space environment, the development of the scanning radiometer proposed a series of high requirements. To this end, the development of high-performance silicon photodiode, the working temperature of 105K mercury telluride mercury detector infrared radiation and cooler, ultra-high vacuum under the long-term scanning drive,
