Abstract

Digital array scanned interferometers (DASI) blend characteristics of a grating spectrometer and a two-beam interferometer for acquisition of hyperspectra. DASI's posses field-widened capabilities that permit very high throughput. Aspects of DASI design, hyperspectra, and data processing methods are presented. In particular, we provide data showing that photon-noise-limited hyperspectra are achievable for DASI data.

摘要

数字阵列扫描干涉仪（DASI）融合了光栅光谱仪和双光束干涉仪的特性，用于获取高光谱。DASI具有拓宽视场的能力，可实现非常高的通量。本文介绍了DASI的设计、高光谱以及数据处理方法。特别是，我们提供的数据表明，DASI数据可实现光子噪声限制的高光谱。
