摘要： A system 100, for determining the velocity of a hammer 120 of a keyboard instrument, with a light transceiver 140 and processing circuitry 160. The light transceiver 140 being configured to transmit a light signal to a hammer 120 to measure a hammer velocity, receive a reflected light signal from the hammer 120 indicative of the velocity of the hammer 120 and send an electrical signal to the processing circuitry 160, where the electrical signal is based on the reflected light signal from the hammer 120. The processing circuitry 160 being configured to receive and process the electrical signal so that a time interval between the electrical signal passing through a first trigger point and a second trigger point and the velocity of the hammer 120 can be determined.
