PHASE SHIFT INFLUENCE RESEARCH OF THE REFERENCE OSCILLATOR SIGNAL ON THE OUTPUT SIGNAL IN HOMODYNE DEMODULATION SCHEME

Subject of Research. Important feature of homodyne demodulation method based on the arctangent function approach is the phase shift between the reference oscillator signal and the interference signal. This phenomenon is caused by propagation delays of impulses in the optical interferometric sensor s...
