摘要
介绍了国内外双色红外探测器的发展现状,并报道了中国电子科技集团公司第十一研究所(以下简称“中电十一所”)自行研制的像元间距为30 m的Si基320×256短/中波双色红外探测器的性能。在77 K测试条件下,短波和中波两个波段的盲元率分别为0.88%和1.47%,平均峰值探测率分别为2.21×10^12 cm·Hz^1/2·W^-1和2.13×10^11 cm·Hz^1/2·W^-1,后截止波长分别为3.129μm和5.285μm,且短波向中波波段的光谱串音为1.38%,中波向短波波段的光谱串音为2.82%。同时,该探测器在双波段具有较好的成像效果,为后续更大面阵、更佳性能的多波段探测器研究提供了基础。
The development of double-color detector at home and abroad is introduced.And the performance of the Si-based 320×256 SW/MW double-color infrared detector developed by the unit is reported.Under the test condition of 77 K,the blind element rates of the short wave(SW)and medium wave(MW)bands are 0.88%and 1.47%respectively.The average peak detection rate are 2.21×10^12 cm·Hz^1/2·W^-1and 2.13×10^11 cm·Hz^1/2·W^-1 respectively.The back cutoff wavelengths are 3.129μm and 5.285μm respectively.The spectral crosstalk from SW to MW band is 1.38%,the crosstalk from MW to SW band is 2.82%.At the same time,the detector has good imaging results in the dual-band,which provides a foundation for further research on multi-band detectors with larger array and better performance.
