Dual-band Fourier-transform Millimeter-wave Spectrometry for In Situ Gas Sensing

The exploration of icy body composition in the solar system has often involved spectroscopic measurements of volatiles detected with remote sensing, such measurements portray materials naturally expelled from the surface that enter the exosphere and potentially escape into space. Variations in the ratio of deuterium and hydrogen in these...

Sub-Orbital Flight Demonstration of a 183/540–600 GHz Hybrid CMOS-InP and CMOS-Schottky-MEMS Limb-Sounder

This paper presents an overview of a sub-orbital flight demonstration with a 183 GHz and 540–600 GHz limb-sounding instrument aboard a stratospheric ballooncraft. The 183 GHz band provides soundings of stratospheric H 2 O and is implemented with a hybrid CMOS-InP receiver architecture which provides excellent sensitivity while remaining compact ...
