Abstract
Disclosed are a system and method for active stabilization of parasitic fringes in optical spectrometers, wherein the spectrometer obtains the transmission spectrum, and a signal processor extracts the etalon drift from the spectral signatures of parasitic fringes. The disclosed approach improves spectrometer accuracy, minimizes drift, and increases time between calibrations.
