US Patent Issued to The Regents of The University of Michigan on July 28 for "Broadband phase-modulated Fourier transform spectroscopy" (Michigan Inventor)

ALEXANDRIA, Va., July 28 -- United States Patent no. 12,693,164, issued on July 28, was assigned to The Regents of The University of Michigan (Ann Arbor, Mich.).

"Broadband phase-modulated Fourier transform spectroscopy" was invented by Jennifer Ogilvie (Ann Arbor, Mich.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase-modulated approach for ultrabroadband Fourier transform electronic spectroscopy is presented. To overcome the bandwidth limitations and spatial chirp introduced by acousto-optic modulators (AOMs), pulses from a 1 micro metre laser are modulated using AOMs prior to continuum generation. This phase modulation is transferred to the continuum generated in an Yttrium Aluminum Garnet crystal. ...
