Paper Abstract

We present a fast recording system of three-dimensional (3D) object based on phase-shifting digital holography. In this system, four-step phase shifting digital holography is employed. The phase modulation for four phase shifts is implemented by an electro-optic modulator that can change the phase of the reference at up to 100 MHz. The image detection is implemented by a C-MOS image sensor. We demonstrate experimentally the acquirement of 3D object information at 250 Hz. We also discuss the accuracy of the reconstructed position when the loss of the information at the image sensor is caused.
