Paper Abstract

This paper surveys the need for oxygen A-band spectroscopy to improve our understanding of clouds and their key role in the climate system. We then report on a novel holographic A-band substrate-guided spectrometer device recently developed at Luminit. This A-band spectrometer prototype is based on an innovative structure of two thick reflection substrate-guided wave-based holograms (SGWHs) that act as dispersive and/or imaging elements to enable a sufficient spectral resolution. The technology is made very attractive by its significantly lower cost compared to currently available systems/devices with similar A-band capability, while providing higher light throughput, a better out-of-band rejection ratio, higher resolution at a smaller size, and better stability and reliability.
