  • Spatially resolved standoff trace chemical sensing using backwards transient absorption spectroscopy
    Patent number: 11099129
    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.
    Type: Grant
    Filed: September 14, 2018
    Date of Patent: August 24, 2021
    Assignee: Brown University
    Inventors: Peter M. Weber, Fedor Rudakov
