Abstract
A torsional vibration measuring instrument has a plurality of reflecting means () arranged with stipulated intervals along surface of a rotator () of which torsional vibration is to be measured; a pulse light irradiating means () for irradiating a repetitive pulse light beam to the reflecting means; and an outgoing-transmitting means () for transmitting the irradiated pulse light beam. The torsional vibration measuring instrument also has a plurality of transmitting-receiving means () for irradiating the transmitted pulse light beam to the reflecting means, and for receiving reflected pulse light beams which have been reflected by the reflecting means; and an incoming-transmitting means () for transmitting the reflected pulse light beams which have been received. The torsional vibration measuring instrument also has a plurality of detecting means () for detecting the reflected pulse light beams which have been transmitted by the incoming-transmitting means; and a signal processing means () for processing pulse output signals which have been outputted from the detecting means and for calculating torsional vibration frequency of the rotator to be measured.
