Title:
SPATIALLY RESOLVED STANDOFF TRACE CHEMICAL SENSING USING BACKWARDS TRANSIENT ABSORPTION SPECTROSCOPY
Document Type and Number:
WIPO Patent Application WO/2019/164552
Kind Code:
A3
Abstract:
A system includes a first laser beam including a pulsed laser emanating from the instrument propagates in the air, wherein the first lase beam is tuned to the wavelength at which a target chemical absorbs, its pulses bringing molecules to an excited state, a second laser beam used to probe target chemicals by transient absorption spectroscopy, wherein the second laser beam is pulsed or continuous, and a detector.
