摘　　要：随着空间遥感技术的发展,实际应用对红外系统探测灵敏度的要求不断提高。其中基于线性雪崩器件的红外成像探测技术能有效提升高帧频应用场合下的探测灵敏度。本文基于512×512的短波红外线性雪崩探测器组件,设计了小口径轻量化红外成像系统,并对其进行了低反偏下的性能测试。测试结果表明,基于线性雪崩型红外探测器的成像系统,在短积分时间下信噪比(Signal-to-Noise Ratio,SNR)的提升与倍增因子M基本呈线性关系,该系统的信噪比是相同口径传统相机的3倍。With the development of space remote sensing technology,the requirements for the detection sensitivity of infrared systems are continuously increasing.The infrared imaging detection technology based on linear avalanche device can effectively improve the detection sensitivity in high frame frequency applications.Based on the short-wave infrared linear avalanche detector assembly of 512×512,a small-aperture and lightweight infrared imaging system is designed and its performance is tested under low reverse bias.The test results show that the increase of signal-to-noise ra⁃tio(SNR)of the imaging system based on the linear avalanche infrared detector is basically linear with the multiplication factor M under short integration time,and the SNR of the system is 3 times that of the traditional camera with the same aperture.
