Abstract:

We describe the design, fabrication and laboratory tests of a Doppler Asymmetric Spatial Heterodyne DASH interferometer for upper atmospheric wind and temperature observations of the Osup 1D 630 nanometer emission. The monolithic interferometer has no moving parts, a large etendue, relaxed fabrication and alignment tolerances and can measure multiple emission lines simultaneously. Laboratory measurements indicate that the design resolution and etendue were achieved and that thermal drifts can be determined with sufficient precision for geophysical applications.
