Abstract

A new type of imaging telescope-spectrometer for surviving the sky aboard a satellite is described. A static Michelson interferometer in front of an objective with 2D-arrays in its focal plane is capable of providing interferograms both for point and extended sources. As an example, the telescope-spectrometer based on the 15-cm telescope of the IKON project and a plane-parallel Ge plate as a beamsplitter may have approximately equals 30 cm(superscript -1 spectral resolution in the range 3 - 20 micrometers . For higher resolution, such an objective interferometer has advantage over a dispersion spectrometer in the signal-to-noise ratio and is free from the disadvantage of an objective prism not providing spectra of extended sources.
