Paper Abstract

In this paper, a kinoform with the characters of two-channel was fabricated by adding quadratic phase factors into Fourier frequency spectrum of object. We adopt the Gerchberg-Saxton (G-S) iterative algorithm and iterate many times between the space field and frequency spectrum field, while keeping the amplitude of frequency spectrum approximately to constant. The phase of the spectrum is quantified. An eight-phase-level kinoform of two-channel is fabricated by using the micro-optical technique. The two separate reconstruction images are clear and the efficiency of the diffraction is 58.5%.
