Paper Abstract

We report on the design and demonstration of a CubeSat-scale spatial heterodyne spectrometer suitable for high-resolution imaging of molecular bands against the earth surface or limb. The demonstration instrument is tuned to a methane absorption band at 1637-1657 nm. The spectral resolution of 0.13 nm is sufficient to resolve individual methane lines, intervening CO2 absorption, and background scattering. The all-transmissive design utilizes volume holographic gratings for high optical efficiency.
