Abstract

We describe a compact, high resolution portable Fourier Transform Spectrometer for use at the Cassegrain focus of an astronomical telescope. The interferometer is dynamically aligned by continuously adjusting the tilt of the fixed mirror under the control of a servo system which monitors laser beams traversing the optical system. Resolution up to 0.02cm^-1 can be obtained in the spectral region 0.8 to 3 μm. Examples of astronomical spectra are given.
