摘要

卫星的地面测试需要验证卫星在真空中运行时的热模型。热电偶广泛用于此测试，但它们只能提供点温度测量。相比之下，真空计量热成像仪可用于测量具有高空间分辨率的大表面积的温度。如果这种系统是一种易于安装的小尺寸、重量和功率(SWaP)设备，那么与在罐内操作的热成像仪相比，它的实用性也会增加。欧空局一般支持和技术计划使国家物理实验室能够开发一种具有真空能力的低SWaP热成像仪，该热成像仪可以在- 40°C至60°C的热真空中提供可跟踪的校准温度测量。计算的仪器校准不确定度小于±0.85°C (k = 2)。

A metrology enabled thermal imager for thermal vacuum testing

ABSTRACT The ground testing of satellites requires the validation of the satellite’s thermal model whilst operational in vacuum. Thermocouples are widely used for this testing, but they are only able to provide a point temperature measurement. In contrast a vacuum capable, metrological thermal imager could be used to measure the temperature across a large surface area with high spatial resolution. Such a system will also have increased utility compared to a thermal imager operated within a canister if it is a low size, weight and power (SWaP) device that can be easily mounted. The ESA General Support and Technology Programme has enabled the National Physical Laboratory to develop a vacuum capable, low SWaP thermal imager that can provide traceable, calibrated temperature measurement in thermal vacuum from −40°C to 60°C. The calculated instrument calibration uncertainty is less than ± 0.85°C (k = 2).
