Paper Abstract

The triangulation method of range and displacement measurements using position sensitive detectors (PSD) is discussed in this paper. The laboratory model of laser triangulation range and displacement sensor built in the Institute of Optoelectronics has been examined and compared with theoretical predictions. The range and resolution of measurements of this sensor dependent on geometrical parameters of the sensor head can be varied in this model. The resolution of 0.5 micrometers of displacement measurement was achieved experimentally in laboratory conditions. The influence of light and electrical noises on linearity and resolution of measurements is discussed.
