Ultrasensitive Mid-Infrared In Situ Spectrometer for Planetary Atmospheric Analysis, Phase I

Completed Technology Project

Project Introduction

Ultrasensitive Mid-Infrared In Situ Spectrometer for Planetary Atmospheric Analysis, Phase I
The Small Business Innovative Research Phase I proposal seeks to develop a compact, robust in situ spectrometer capable of detecting multiple gas-phase species in planetary atmospheres with ultra-high sensitivity and selectivity. This instrument will employ a novel room-temperature, widely tunable mid-infrared laser source in conjunction with cavity ringdown spectroscopy. During Phase I, the 3.3 to 3.5 ��m spectral region will be targeted, which overlaps the spectral absorption features of variety of hydrocarbons, including methane, ethane, and formaldehyde. The ultra-high sensitivity of the proposed system will enable these species to be detected at concentrations below 7*107/cm3 per minute, which corresponds to a detection limit of <30 pptv in Earth?s atmosphere.
