Design of the integrated sensor system for two-dimension position based on CCD

In this Article, a kind of design philosophy of a integrated sensor system for two-dimension position is presented. The sensing unit of this system is a two-dimension CCD (Charge-Coupled Device). Through increasing the signal-to-noise ratio of a constructed specific lightspot target and performing optical filter, the exported full video image signal of CCD which includes a group of isolated positive pulse caused by the target is formed. Through combinational logic and sequential logic processing to the full video signal, the target image's two-dimension position on the light sensitive layer of CCD can be generated. Finally, the specific fightspot target's relative two-dimension position in the visual field is gained. In addition, a typical application of the system in the computer information processing field are presented as well.
