| Abstract: | The laser Omni-directional bar code scanner introduced here mainly consists of a holographic disk which as a plane optical element is to realize the laser beam deflection and focusing , as well as a series of mirrors designed for a scanning space. For high speed real time detection and recognition of weak light signals, the analog circuits and digital circuits are also designed, the design parameters related to the holographic disk and some experimental results are shown. |
