Abstract

The kinoform¹ is a phase-only computer-generated hologram which has some advantages because of its high efficiency. Some studies on the optimization of the phase distribution in the kinoform has already been reported by several authors to the present^2,3. In most of studies, the iterative method were chiefly adopted to optimize the phase distribution in the kinoform. However, in the iterative method, a system to be optimized may be trapped the local minimum , so that the global minimum is not always found. The optimization of a simple kinoform by the simulated annealing(SA) algorithm⁴ has already been studied by Turunen et al.⁵. The SA algorithm is a method of finding the global minimum in a system to be optimized.
