摘要： Photodiodes in combination with an amplifier of transimpedance configuration provides an optical vibration detector having a linear frequency response with a light emitter and sensor of sufficiently small size to be inserted between strings of a musical instrument in order to provide signals suitable for amplification. The frequencies of vibrating strings of a musical instrument can be converted in accordance with either of two converter embodiments to control a music synthesizer, an automatic music transcription arrangement or the like.
