Abstract:

The method of designing binary optical element (BOE) is proposed to realize Achromatic Optical Variable Device (AOVD). The distribution of confined slot was used as target object and then the binary phase structure was calculated by Iterative Fourier Algorithm (IFTA). The structure had directional diffractive character and acted as the cell of AOVD. Two different datum schemes were adopted to design AOVDs of different configurations. AOVD was fabricated by SVG-LDW04 lithography system in patternby-pattern mode and vector writing mode respectively. The minimum width of phase structure of AVOD is 2 μm and the photos of fabricated AVODs were also given. The results show that the directional diffractive binary phase structure was achromatic and apt for hot embossing and offers a new method for AVOD.
