Paper Abstract

Position sensitive device (PSD) is a kind of new photoelectric device which would produce different electrical signals when the inputting light point irradiates at the different position of PSD surface. In new on-line measurement system of displacement, a laser diode emits the light to measured object and PSD detects the different position of the light point which reflects from the measured object because of its displacement change so that the displacement of object can be measured. This paper will present the principle and schematic diagram of measurement device and introduce the circuits of measuring device. At last the results of experiment are also shown and discussed.
