Paper Abstract

This instrument is a new form of non-dispersive gas correlation sensor. It was designed to measure the emission from atmospheric gases in the stratosphere and mesosphere from a space platform. The measurement technique involves the pressure cycling of a sample of the gas to be detected in a small optical cavity through which incoming radiation is passed. The principles of pressure modulation technique and several areas of terrestial applications will be discussed in the paper.
