Characterization of a Hyperspectral Imager

Abstract

A spectral imager constructs a three dimensional (two spatial and one spectral) image from a series of two dimensional images. This paper discusses a technique for spectral imaging that multiplexes the spatial and spectral information on a staring focal plane, then demultiplexes the resulting imagery to obtain the spectral image. This approach has high optical throughput and is robust to focal plane array (FPA) nonuniformities. This presentation is the third in a series to the IRIS passive sensors community. Previously we introduced the hardware and discussed the reconstruction algorithm in detail. Here we review the hardware and present experimental results.
