Paper Abstract

Results of a feasibility study aimed at the development of a high resolution imaging interferometer (HRII) using Fourier transform spectroscopy are reported. The proposed instrument has three spectral ranges: a visible and near infrared (VNIR) from 0.45 to 1.0 micron, a short wave infrared (SWIR) from 1.0 to 2.5 microns, and the optional thermal infrared (TIR) from 8.0 to 12.5 microns. The spatial resolution on ground is proposed to be 40 m for VNIR and SWIR, and 200 m for TIR; the weight of the instrument will be less than 150 kg. The main conclusion of the study is that Fourier transform spectroscopy is well suited for imaging spectroscopy in space instrumentation.
