Claims20
An optoelectronic pickup, comprising:
- a first light source configured to direct light to impinge an instrument string of a musical instrument;
- a second light source configured to direct light to impinge the string;
- a first photosensor configured to detect light emitted by the first light source and reflected from the string;
- a second photosensor configured to detect light emitted by the second light source and reflected from the string;
- 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.
