First and second signals corresponding to at least two beams may be generated or received. The first and second signals may be complementary, and may be based on signals provided by one or more photo detectors that receive the at least two beams after the beams return from a sensing structure. The first signal and the second signal may be subtracted to produce a third signal. A position of the sensing structure may be adjusted to cause the third signal to reach a first value, where the adjusting may be performed based on the third signal, and an audio output signal may be provided based on the third signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal processing within an optical microphone","description":"Method for performing signal processing for an optical microphone.
