The kinoform is attractive because of the high diffraction efficiency and the manner of on-axial reconstruction. In this work, we use the Gerchberg-Saxton iterative algorithms to optimize phase distribution of the kinoform. The phase in each pixel is then quantized into a set of eight-level values. The surface of quartz glass plate is etched to a depth determined by the corresponding phase retard, forming a kinform with stair-like surface relief. The optical experiments are canied out. The on-axial reconstruction image with high fidelity and high efficiency is obtained.
