Abstract

We present the recent development of a compact Michelson-like interferometer for an imaging Fourier Transform Spectrometer (IFTS). The interferometer has a mass of less than 600 g and dimensions of about 60 mm x 90 mm x 100 mm. It is designed to be stiff to reduce its sensitivity to vibrations. Its maximum optical path difference is 1 cm. Despite its small size it can support an etendue of 9.2x10^-7 m² sr. This interferometer is well suited to serve as the modulator for a small IFTS when mass and volume are restricted such as onboard planetary probes, UAV, etc. This interferometer can be adapted to a wide variety of infrared imaging detectors. It is a building block upon which can be designed a large range of custom infrared imaging spectrometers.
