    摘要： A fringe locking subsystem for an optical sensing cavity is provided. The subsystem comprises one or more photo detectors that detect a reference signal and a cavity signal; a first amplifier that generates a calculated differential between the reference signal and the cavity signal; a lock-in amplifier that generates a modulation signal based on the calculated differential; and a controller that adjusts a distance within the cavity based on the modulation signal.

    摘要： A multimode detection system for detecting one or more samples is provided. The detection system comprises an electromagnetic radiation source, a reference arm, and a sample arm comprising a sensing substrate having a plurality of sample fields, wherein the sample fields are configured to receive the one or more samples. The system further comprises a phase difference generator configured to introduce pathlength differences in the reference arm, sample arm, or both, a spatial light modulator operatively coupled to the reference arm, sample arm, or both, wherein the spatial light modulator is configured to modulate incident radiation, resultant radiation, or both in the reference arm, sample arm, or both, and an imaging spectrometer configured to discriminate between two or more spatially separated sample en two or more spatially separated sample fields.
