摘要： A low-cost and high-compatibility optical pickup including a light source, one set of optical sensors, and a controller. The light source illuminates a string assembled on an instrument. The set of optical sensors corresponding to the light source is provided to sense the shading of the string. The controller supplies the sensed data from the set of optical sensors to a system host for recognition of the melody played on the string. Considering the other strings assembled on the instrument, the optical pickup includes other sets of optical sensors to sense the shading of the other strings which are also illuminated by the light source. The controller also supplies the sensed data of the other sets of optical sensors to the system host for recognition of the melody played on the other strings.
