Abstract—This paper describes the design and characterization
of a 134-pixel linear array sensor for three-dimensional measure-
ments based on both multiple-pulse indirect-time-of-flight (ITOF)
and optical triangulation (OT) techniques. In OT mode, a winner-
take-all (WTA) stage allows for a fast localization of the spot posi-
tion along the pixel array so that only useful pixels are selec
