为考核光学遥感器在空间环境中各项功能的适应性,确保在空间环境条件的有效性和可靠性,作者研制了ZM3000光学遥感器空间环境模拟试验设备。研制内容包括:内径为Φ3000mm、直段长为5000mm的卧式圆柱体真空容器;不锈钢管与铜翅片焊接成的管板结构热沉;无油真空抽气;最低温度达80K的单相密闭液氮循环流程;温度范围为-60℃至+100℃的机械制冷与红外加热调温热沉;数据采集与控制管理等分系统。结果表明:该设备满足了光学遥感器在地面进行空间环境模拟试验和光学性能测试的要求。

In order to assess the space optical sensor＇s thermal optical characteristics, verify the sensor＇s performance and insure the sensor＇s adaptability against space and thermal environment in the space environment simulation test, ZM3000 space environment simulation test facility was developed. The developments included the horizontally - laid cylinder of 3000mm inner diameter by 5000mm long vacuum chamber, shroud of stainless steel pipe welded with copper fins, oil -free evacuation, the monophase closed -loop liquid nitrogen circulating with the lowest temperature at 80K, alcohol cooling and infrared heating tem- perature adjustable shroud with the temperature range of -60~C to ＋ 100~C, as well as data acquisition and control subsystem. It was satisfied for ZM3000 facility to be applied to the space environment simulation and thermal optics tests of the optical remote sensor in ground environment.
