Paper Abstract

A new kind of method generating kinetic diffraction grating image is introduced in this paper. Its main property is that the technique of real time dividing light is used in the system. The work efficiency is raised much more than other method, and the angles between two thin beams for generating pixels are successive variable. The encoding principle of kinetic diffraction grating image is discussed. The concept of the grating spectral pallet is first proposed and the sampler of grating spectral pallet is given. The image can be generated to give satisfaction to custom with this grating spectral pallet. The image color can be in accord with the original image color, because there are as many grating spectral pallets as computer spectral pallets. The relation between the number of pallet and the angle of two thin beams is discussed. This kind of image is of high technology, short developing circle time and the properties of being kinetic and visible in 360 degree. It will be widely used in laser anti-counterfeiting, decorating and packing fields.
