This paper describes the design and characterization of a linear array for three-dimensional measurements based on both multiple-pulse Indirect-Time-Of-Flight (ITOF) and Optical Triangulation (OT) techniques. The 128-pixel array has been fabricated in a standard 0.35um, 3.3-V CMOS technology and the chip dimensions are 4.5x3.3-mm2. The distance measurement with cooperative targets in the 2-8 m range has been successfully performed with a worst case precision better than 4 cm in the ITOF modality. Preliminary test confirmed also the validity of the OT mode, reporting a depth resolution of 100 um at 1 m

Abstract

This paper describes the design and characterization of a linear array for three-dimensional measurements based on both multiple-pulse Indirect-Time-Of-Flight (ITOF) and Optical Triangulation (OT) techniques. The 128-pixel array has been fabricated in a standard 0.35um, 3.3-V CMOS technology and the chip dimensions are 4.5x3.3-mm2. The distance measurement with cooperative targets in the 2-8 m range has been successfully performed with a worst case precision better than 4 cm in the ITOF modality. Preliminary test confirmed also the validity of the OT mode, reporting a depth resolution of 100 um at 1 m
