Abstract

The DOE-HOE's, made by Dot-matrix technology, have found application in various areas, such as security, protection of various goods from faking, packing etc. These holograms contain a set of pixels with diffraction gratings with different spatial frequencies and orientation. The process of manufacturing represents a consecutive pixels exposure. The pixels quantity is great (about 10⁵-10⁶), that's why master-shim manufacturing requires considerable time. Spatial frequency and orientation of gratings change because of mechanical shift of elements. For acceleration of the recording process it is necessary to replace slow mechanical devices with high-speed ones. This paper proposes a possible solution of this problem, by using a spatial light modulator. This paper describes the technique and results of calculations of optical components parameters.
