| Abstract: | This paper presents a method of generation the cone wave by Com puter Generated Hologram (CGH). When the hologram is illuminated by a plane monochromatic wave, the centre of diffraction pattern of the hologram forms a straight line for alignment. In this paper the transmittanoe of cone wave as well as alignment precision and alignment distance are theoretically analyzed. The experimental results are given. |
