Development of an Imaging Fourier Transform Spectrometer

Abstract

This study established the feasibility of an Infrared Imaging Fourier Transform Spectrometer (IRIFTS), and the development of a working prototype is described herein. The IRIFTS is a measurement system that can simultaneously acquire spatial, spectral, and temporal IR radiance information. The theory of the components is presented, a more general half-angle obliquity limit is derived for the Fourier Transform Spectrometer (FTS), and the theoretical feasibility of the concept is shown. Commercially available components were acquired, interfaces were constructed, and a one dimensional (spatial) imaging FTS system prototype was assembled. Results are presented for the operation of the system. Keywords: Spectroscopy; Infrared; Technology; speedometer.
