Paper Abstract

Laser beam deflection can be obtained by using holographic gratings. For example, a constant-frequency grating rotating normal to the laser beam can scan the laser beam along an arc of a circle. Or, by moving an off-axis zone plate across the laser beam, the linear variation in the spatial frequencies of the zone plate will produce a raster scan line. Even more complicated scanned patterns can be obtained by making the proper computer-generated holograms. In this paper the principle of holographic grating scanner and the consider-ations in making computer-generated holograms to produce beam deflections in two directions will be discussed. Some experimental results will be shown.
