Optical Pickup for a Musical Instrument |
摘要 |
This invention relates to an optical pickup for a musical instrument based on one or more than one Bragg grating. In one embodiment the optical pickup includes at least one Bragg grating in physical contact with a vibrating structure of the musical instrument so as to receive acoustic vibration associated with the musical instrument being played, such that a spectrum of the Bragg grating is modulated upon receipt of the acoustic vibration. A light signal reflected from the at least one Bragg grating may be amplified and the output may be directed to a loud speaker or other real-time output device. The output may also be directed to a data acquisition system for storage and further processing. The optical pickup may include two Bragg gratings arranged as an optical cavity.
