Design, Validation and Prototype Testing of a High Resolution All- Reflection Michelson Interferometer for Solar Occultation Measurements of the OI 1304-A Triplet Emission

Abstract

A prototype All-Reflection Michelson Interferometer (AMI) was tested using two different diffraction gratings and a variety of light sources. The original design used a focusing lens, a pinhole aperture and an off-axis parabolic mirror for collimation, a plane diffraction grating and two plane mirrors to divide and recombine the light and a CCD camera to record the interference pattern. Interference patterns were recorded and analyzed in the Interactive Data Language (IDL) using Fourier transform techniques. The design was then modified to approximate an actual instrument for remote observations of the atomic oxygen 1304-A triplet emission. The results of numerous experiments using both the original and modified instruments verified the feasibility of using the AMI as a compact, lightweight, high resolution instrument for use on sounding rocket or satellite platforms.
