Claim Text:
1. An optoelectronic pickup, comprising: a first light source and a second light source each configured to direct light to impinge the same instrument string of a musical instrument, the first light source laterally offset from a longitudinal axis of the string in a first direction and the second light source laterally offset from the longitudinal axis of the string in a second direction opposite the first direction; a first photosensor configured to detect light emitted by the first light source and reflected from the string, the first photosensor laterally offset from the longitudinal axis of the string in the first direction, the first light source and the first photosensor defining a first light source-photosensor pair; a second photosensor configured to detect light emitted by the second light source and reflected from the string, the second photosensor laterally offset from the longitudinal axis of the string in the second direction, the second light source and the second photosensor defining a second light source-photosensor pair; wherein the first light source and the first photosensor are angled towards each other, and the second light source and the second photosensor are angled towards each other; and wherein the first light source-photosensor pair is axially offset from the second light source-photosensor pair relative to the longitudinal axis of the string.
