An Improved Synthesis Phase Unwrapping Method Based on Three-Frequency Heterodyne

An improved three-frequency heterodyne synthesis phase unwrapping method is proposed to improve the measurement accuracy through phase difference and phase sum operations. This method can reduce the effect of noise and increase the equivalent phase frequency. According to the distribution found in t...
