摘要
为满足高光谱遥感应用对分光元件宽工作光谱范围的要求,根据Fabry-Perot(F-P)可调谐滤波器出现透射率极大值的相位条件,通过划分滤波器的工作光谱范围,选定干涉级数,确定F-P腔的腔长变化区间,来抑制F-P可调谐滤波器的多级透射峰。该方法可以有效拓展F-P可调谐滤波器的自由光谱范围,使其光谱扫描特性满足高光谱遥感应用要求。
To satisfy the need of a wide working spectral range for spectral-splitting elements in hyperspectral remote sensing applications,a method for suppressing multi-order transmission peaks of tunable Fabry-Perot filter(TFPF)is proposed.According to the phase conditions of transmission maximum occurrence,the effect of multi-order transmission peaks is eliminated by partition of working spectral range,designation of interference order and determination of cavity length variation region of TFPF.The method can effectively extend the free spectral range(FSR)TFPF and make its spectral scanning properties meet the application requirements of hyperspectral remote sensing.
