In this paper, we present a fast hologram pattern generation method to overcome accumulation problem of point source based method. Proposed method consists of two steps. In the first step, 2D projection of wave field for 3D object is calculated by radial symmetric interpolation (RSI) method to the multiple reference depth planes. Then in the second step, each 2D wave field is translated toward SLM plane by FFT based algorithm. Final hologram pattern is obtained by adding them. The effectiveness of method is proved by computer simulation and optical experiment. Experimental results show that proposed method is 3878 times faster than analytic method, and 226 times faster than RSI method.
