Title: Analysis and Implementation of Phase Modulation and Demodulation Technology for Optic Micro Cavity
Abstract: Theoretical analysis of the phase modulation and demodulation principles of the lock-in amplifier was put forward.The characteristics of the resonant cavity and the phase modulation and demodulation simulations were analyzed by using multi-beam interference.The phase modulation and demodulation system of the micro optical cavity was designed.The test results verify the feasibility of the modulation and demodulation system.And the low-frequency modulation and demodulation signal and the sideband signal of the optical resonant cavity were obtained.
