Development of an Imaging Fourier Transform Spectrometer

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.
