Multi-Wavelength Interferometric Absolute Distance Measurement and Dynamic Demodulation Error Compensation

This paper presents an absolute distance measurement system based on three-wavelength synchronous phase-shifting interferometry. A synthetic wavelength chain is established using three semiconductor lasers in an all-fiber Fizeau interferometer. By integrating a piezoelectric transducer (PZT)-driven...
