PSD Position Sensing Physics Lab Experiments Setup by ATICO EXPORT

This experiment system is designed for studying the operating principles and characteristics of Position Sensitive Detectors (PSD). PSDs are photoelectric detection devices capable of determining the position of the energy center of a light spot incident on the photosensitive surface. With fast response times and high measurement accuracy, PSDs are widely used in position measurement and optical sensing applications. The system utilizes analog signal processing techniques, including current-to-voltage conversion and operational amplifier circuits, to accurately determine the position of the incident light spot.
