  • Computationally-assisted multi-heterodyne spectroscopy
    Patent number: 10656016
    Abstract: According to one aspect, a multi-heterodyne system is disclosed, which comprises a first laser source for generating multi-mode radiation having a frequency spectrum characterized by a first plurality of phase coherent frequencies, and a second laser source for generating multi-mode radiation having a frequency spectrum characterized by a second plurality of phase coherent frequencies. The system further comprises at least one detector for detecting a combination of the multi-mode radiation generated by the first and second laser sources so as to provide a multi-heterodyne signal having a frequency spectrum characterized by a plurality of beat frequencies, each beat frequency corresponding to a pairwise difference in the first and second plurality of phase coherent frequencies.
    Type: Grant
    Filed: October 1, 2018
    Date of Patent: May 19, 2020
    Assignee: Massachusetts Institute of Technology
    Inventors: David Burghoff, Yang Yang, Qing Hu
