Paper Abstract

A linear 128-photosensor array in a complimentary metal-oxide semiconductor (CMOS) standard technology is presented. The characteristics of the pixels are high voltage at the output in the range of 0 to 3.5 V and a pixel memory with the possibility of multiple readouts without significant degradation of information. The ASIC also includes a selection logic to select the pixel to be read. Using this CMOS photodetector array, we also present a low-cost prototype for the distance measurement and 3-D reconstruction of near and small objects, where the optical triangulation method used is appropriate. Good acquisition results are obtained in the experimental test.
