Abstract
In the present paper we will discuss a smart optical sensor that has been designed for the purpose of sheet of light range imaging. The sensor consists of an array of Position Sensitive Detectors (PSD’s). The PSD’s have a length of 20mm and a width of 20μm. The pitch in the array is 28μm. This PSD array is used to record the cross sectional line of a sheet of laserlight with an object. Three dimensional information is computed using triangulation. A complete surface can be measured by sweeping the sheet of light over the object. On-chip electronics deal with low-pass filtering and multiplexing of the sensor signals.
