摘要：
A newly developed plane optical element-holographic disc as an omnidirectional scanner for bar code auto-recognition, with which the incident laser beam could be realized beam deflection and focus is described. The original design parameters are also given. The experiment shows that within the length of 500mm, the height of the are of scanning line will not exceed 12mm and the focused spot size is 0.2mm averagely in this paper.
