A New Angular Displacement Transducer

摘要

A miniature non-contacting displacement transducer is described, designed to measure the static and dynamic angular rotation of a shaft. The measurement technique uses a specially constructed fibre-optic probe, an infra-red light source and a receiver. Amplitude measurements within a 0 + or - 180 deg. range may be made for frequencies from 0-500 Hz. The transducer has continuous resolution, producing a voltage output related to instantaneous angular displacement. (Author)
