ABSTRACT:
A optoelectronic pickup for a musical instrument includes at least one light source which directs light to impinge a string of the musical instrument in at least one photoreceiver located to detect the reflected light, so as to generate an electrical signal that is responsive to string vibrations. A number of dissimilar filter approaches are included to control undesired effects of spurious light, the filter approaches may be structure-based, signal processing-based, and/or optics-based.
