Abstract
Kinoform is a synthesized phase diffractive optical element which allows to reconstruct image by its illumination with plane wave similarly to hologram. All iterative methods of kinoform synthesis use random phase distribution at start as first approximation of future kinoform. Faster convergence and lower synthesis error can be achieved if in place of random phase distribution computer synthesized phase hologram is used. However, this leads to necessity of spatial separation of first and minus first diffraction orders. Results of experiments on kinoform synthesis using phase Fourier hologram as basis for iterative algorithm and comparison with basic technique are presented.
