Paper Abstract

In this article, a kind of design philosophy of a integrated sensor system for 2D position is presented. The sensing unit of this system is a 2D CCD. Through increasing the signal- to-noise ratio of a constructed specific lightspot target and performing optical filter, and 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 2D position on the light CCD can be generated. Finally, the specific lightspot target's relatively 2D 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.
