我们提出了一个初步的分析和设计框架的评估和优化的红外，成像空间外差光谱仪（SHS）的电光系统。与传统的干涉光谱仪相适应，SHS建模需要一个集成的分析环境，用于严格评估由于检测过程，检测噪声，系统运动，检索算法和校准算法引起的系统误差传播。分析工具提供关键系统参数和组件的优化，包括：（1）光学孔径、f数和光谱透射，（2）SHS干涉仪光栅和Littrow参数，以及（3）像平面要求以及冷屏蔽、光学滤波和焦平面尺寸、像素尺寸和量子效率，（4）SHS空间和时间采样参数，以及（5）检索和校准算法问题。
We present a preliminary analysis and design framework developed for the evaluation and optimization of infrared, Imaging Spatial Heterodyne Spectrometer (SHS) electro-optic systems. Commensurate with conventional interferometric spectrometers, SHS modeling requires an integrated analysis environment for rigorous evaluation of system error propagation due to detection process, detection noise, system motion, retrieval algorithm and calibration algorithm. The analysis tools provide for optimization of critical system parameters and components including: (1) optical aperture, f-number, and spectral transmission, (2) SHS interferometer grating and Littrow parameters, and (3) image plane requirements as well as cold shield, optical filtering, and focal-plane dimensions, pixel dimensions and quantum efficiency, (4) SHS spatial and temporal sampling parameters, and (5) retrieval and calibration algorithm issues.
