摘要
An illustrative interferometric system with high-fidelity optical phase demodulation includes a receiver having a fiberoptic coupler that produces optical mterferometry signals having mutual phase separations of 120° and balanced photo- detectors that each produce an electrical difference signal based on a respective pair of said optical mterferometry signals. The system further includes circuitry that converts the electrical difference signals into measurements of an interferometric phase.
