Optimized Position Sensors for Flying-Spot Active Triangulation Systems

Abstract

A description of the integrated sensors developed for flying-spot active triangulation will be given. All the sensors have been fabricated using standard CMOS technology that allows the monolithic integration of photo-sensors, together with readout circuits, and digital signal processors. Position sensors are categorized into two classes that allow a better understanding of the pros and cons of each one. A description of the proposed position sensor that is optimized for accurate and fast 3D acquisition is given alongside some experimental result
