摘要
报道了集成碲镉汞红外双色焦平面探测芯片光谱特性研究的初步结果.针对HgCdTe红外双色探测原型芯片短波响应光谱偏窄的现象,展开了双色探测芯片光谱特性与结构特性内在关系的理论分析和实验研究,发现了SW响应光谱窄的起因和解决思路。
Some recent results of spectral characteristic study of integrated HgCdTe （ mercury cadmium telluride） infrared two-color detector arrays were presented firstly. Many further investigations of spectral and structural characteristics were fo- cused on SW （short wavelength） response of the preliminary two-color detection arrays Which exhibited a narrow spectrum. The reason and solution of SW spectrum with small FWHM （full width of half maximum） were then found, and the proper spectrum of two-color detector with an improved structure was obtained. The results are as good as expected.
