Abstract
This work describes the design and realization of a laser sensor dedicated to the measurement of the finger position on a musical instrument, like a guitar. The working principle of the sensor is optical triangulation: the system is realized by six lasers, multiplexed in time, and four Position Sensing Detectors. The speed and the accuracy of the proposed sensor well satisfy the application requirements.
