摘要
文章报道了空间多光谱扫描仪红外波段多元光导碲镉汞探测器的研制与优值。重点研究并解决了多元器件光谱曲线不一致性的问题,简述了器件的优值波段响应率RΔλ1,波段探测率DΔλ和单色响应率Rλ的测试定标方法,以及器件按空间环境使用要求经历老炼和环境条件试验的情况。测试结果表明多元件性能稳定可靠,各项指标均达到了空间多光谱扫描仪的技术要求。
The development and figure of merit of photoconductive HgCdTe multielement detector used in multi-spectral scanner in thermal IR band are reported in this paper. It focuses on the method of resolving the non-uniformity of spectral response curve for multielement device. The testing and scaling methods on the responsivity RΔλ1 of figure of merit band, the detectivity DΔλ1 of band and the responsivity Rλ of monochrome band are also discussed briefly, as well as the situation of aging test and environmental test under space environment condition. The test result shows that the technical index of the multielement device can meet the requirements of space multispectral scanner and its performance is stable and reliable.
