  • Cavity ring-down spectroscopy having interleaved data acquisition for interference mitigation
    Patent number: 11035728
    Abstract: Interleaved data acquisition in optical spectroscopy is used to provide interference correction for time-varying interference. Measurements at a reference frequency are used to provide an estimate of the interference. These reference measurements are interleaved with the remaining measurements in order to provide estimates of the interference vs. time at relevant times. The interference being corrected can be spectrally structured or unstructured.
    Type: Grant

    Date of Patent: June 15, 2021
    Assignee: Picarro, Inc.
