A new fiber-optic interferometer fringe projection with the integrating bucket method is presented. This method is based on the sinusoidal phase-modulating technique and makes use of Mach–Zehnder interferometer structure and Young’s double pinhole interference principle to achieve interference fringe projection. Here, we consider the modulated signal with the modulation intensity of laser (companion amplitude modulation) in the calculation directly, adjust the optimal value of to accommodate different , and calculate the initial phase with phase generated carrier technology at the same time. Preliminary results from the optimum phase modulation and initial phase are discussed.
