A Monolithic, Non-Field-Widened Spatial Heterodyne Spectrometer for Solar System Exploration, Phase I

Completed Technology Project

Project Introduction

A Monolithic, Non-Field-Widened Spatial Heterodyne Spectrometer for Solar System Exploration, Phase I
The goal of this project is to produce a monolithic Spatial Heterodyne Spectrometer (a Fourier Transform Interferometer) for use in Solar System exploration. In Phase I, the gratings and beamsplitter for a visible-wavelength SHS (operating near 633 nm) will be constructed and aligned, to demonstrate that an isomorphic IR monolith can function. A complete IR monolith, with novel construction, will follow in Phase II. The viability of both the Phase I and Phase II constructs will be shown by detecting and analyzing interferograms for a monochromatic and a polychromatic source. The analysis of that data will use Fourier Transform code written by the experimenters in Interactive Data Language (IDL). It is expected that, in each phase, complete spectra of both sources over the spectral range of the instrument will be readily obtained from these tests. The Phase II instrument will be available for further research More »
