Abstract

Computer generated hologram as a basic optical diffractive element can be used widely in many fields. In designing computer generated holograms, a coding and Fourier domain iterative optimization method are introduced in the paper. Each pair of real and imaginary part in the Fourier spectrum of an image is coded by a weighted cosine function. Then the binary computer generated hologram corresponds to the coefficient distribution of the cosine extension. Moreover we define a Fourier domain mean-squared error between the Fourier spectrum of an image and the binary computer generated hologram. By minimizing the Fourier domain mean- squared error iterative, we can implement the hologram coding and optimization.
