This thesis investigates the design of a digital fiber-optic interferometric demodulator based upon a passive symmetric combination of signals produced by an interferometer terminated with a 3x3 optical coupler. The demodulator was implemented using a digital signal processing (DSP) board based upon a TMS320C31 DSP processor. The demodulator was tested using signals produced by a set of interferometric simulators which used an analog AD639 trigonometric chip. A goal of this thesis was to demonstrate an improved noise floor at low frequencies as compared with a similar analog implementation. |
