Several investigations has been conducted to determine the best way to improve the reconstruction of Kinoform images. Many of these investigations, however, forcused on the use of the iterative algorithm method, and little attention was paid to the use of the error-diffusion method. Most of the studies that have focused on the error-diffusion method examined its use in relation to binary-phase quantized holograms, not kinoform. Moreover, the relationship between an input object's position and the diffusion coefficients has not been reported. This is because the error-diffusion method reconstructed to separate the object as for the noise that originated in the quantization error. This paper discribes the application of a error-diffusion method that uses a complex number for the diffusion coefficient a kinoform. Results of Computer Simulation showd that the error diffusion method is superior to the iterative algorithm method for image reconstruction iterative algorithm because less processing. they also demonstrared that the restriction on the position of an object can be eased by changing the diffusion coefficient on the basis of that object's position.
