SHIMS -- A Spatial Heterodyne Interferometer for Methane Sounding, Phase I

Completed Technology Project

Project Introduction

SHIMS -- A Spatial Heterodyne Interferometer for Methane Sounding, Phase I
This project develops the Spatial Heterodyne Interferometer for Methane Sounding (SHIMS), a lightweight, compact, robust spectrometer system for remote sensing of methane (CH4) via a series of absorption lines in the ~tetradecad~, over the range 1.6 to 1.7 microns. This instrument will be incorporated into a satellite package, and is capable of being scaled into a 2- to 3-U CubeSat payload size. The end result of this project will be: (1) a full nadir-viewing near IR spectrometer system, featuring the first-ever high-resolution monolithic Spatial Heterodyne Spectrometer for the near IR range; and, (2) a separate prototype of the first-ever SHS monolith with dedicated, built-in output optics which attach directly to the SHS monolith and to a detector via a standard c-mount adapter. This innovation will circumvent the need for the user to incorporate separate optics outside the monolith, making the unit even more end-user-ready. More »
