Extending Remote Gas Sensing Range

a. Extending Remote Gas Sensing Range Fast spectral identification of multiple chemical species is essential when signals are short lived or in constant flux. In response to this, a variety of active sensing systems have been investigated in the past. For example, frequency comb technologies have been shown to provide large spectral coverage while maintaining high resolution [1]. Proposed efforts under this topic should seek to extend the range of sensing systems that can identify multiple gaseous species beyond 1km distance-to-target [2]. High priority should be given to the maximization of signal-to-noise ratios. Questions Contact: Chris Ramos, Christopher.ramos@nnsa.doe.gov
