800×2元线列短波红外二类水体大气校正 800×2 linear array detector InGaAs InGaAs SWIR caseⅡwater atmospheric correction

摘要

为了对近海浑浊的二类水体水色遥感进行大气校正，采用国产 800×2短波红外 InGaAs探测器、窄带滤光片和透射式像方远心光学系统研制了 1.232～1.252 .m和 1.630～1.654 .m双波段短波红外推扫成像系统。该成像系统具备在轨注入工作参数的能力，可灵活调节成像工作模式。经测试，双波段线阵短波红外成像系统的 MTF、信噪比以及光谱响应均达到较高性能，有望提供一种有效的二类水体大气校正手段。

Abstract

In order to apply atmospheric correction to the turbid coastal case II water, a SWIR dual band push-broom imaging system with response from 1.232 to 1.252 .m and 1.630 to 1.654 .m is designed and implemented. It consists of a homemade 800×2 InGaAs SWIR FPA, narrow bandpass filter and image telecentric optical system with the ability of on orbit injection of working parameters which can be used to adjust the working mode of the imaging system flexibly. Tests show the imaging system’s MTF, SNR and spectral response are perfect. It’s expected to provide an effective atmospheric correction method for caseⅡ water.
