Abstract

In this paper we compare the performance for effluent gas detection of three types of imaging spectrometers. The spectrometers compared are the grating and Fourier Transform (FTS) for their wide implementation and the Acousto-Optic Tunable Filter (AOTF) for its unique feature of spectral tunability. The analysis is performed in the thermal emission region of spectra using Raytheon developed software simulation and modeling tools. The paper concludes with a proposed system design and architecture considerations for an AOTF-based hyperspectral and polarimetric imaging sensor for airborne and spaceborne platforms.
