Compressed multiline spectroscopic trace gas sensing

Figure by Sebastiaan Haffert

We develop an instrument concept in which spectral lines over a very wide spectral range can be combined into a single, average spectral line. An Acousto-Optical Filter serves as a programmable Bragg grating. We design imaging instruments that can be configured in a flexible manner to very efficiently detect and measure a particular trace gas for a particular scene, by combining the many individual spectral lines of a molecular band. Applications include trace-gas measurements in the Earth’s atmosphere and exoplanet characterization.
