Compact imaging spectrometer combining Fourier transform spectroscopy with a Fabry-Perot interferometer

Opt Express. 2009 May 11;17(10):8319-31. doi: 10.1364/oe.17.008319.

Abstract

An imaging spectrometer based on a Fabry-Perot interferometer is presented. The Fabry-Perot interferometer scans the mirror distance up to contact and the intensity modulated light signal is transformed using a Fourier Transform based algorithm, as the Michelson based Fourier Transform Spectrometers does. The resulting instrument has the advantage of a compact, high numerical aperture, high luminosity hyperspectral imaging device. Theory of operation is described along with one experimental realization and preliminary results.
