Abstract
A measurement sensor comprising a PSD () as an optoelectronic receiver, a transmitter () for generating spots (), optics () for reproducing the spots (') on the PSD () and means () for processing output signals (I, I) generated by said PSD () and for controlling the transmitter () depending on the processed output signals (I, I) in order to measure the distance between the target () and the sensor by a triangulation technique is disclose closed. The transmitter comprises at least two optoelectronic signal sources () for projecting at least two spots () independent from each other on a target (), the means () comprising a digitally controlled potentiometer () for balancing the output signals (I, I) and a digital processor () adapted for controlling the potentiometer ().
