Abstract

Based on the theory of Michelson optical fiber interferometer and Doppler frequency shift equations, author proposed a new optical fiber non-contact velocity measurement technique. And the new method was successfully used in flyer velocity measuring test. In the test, the optic fiber interferometer system not only measured the velocity which was around 3km/s but also acquired the full explosion progress of flyer plates. System adopts large pupil optical transceiver devices to improve the anti-deflection capability compared with the traditional self-focusing lens. Optical fiber noncontact velocity measurement equipment which was simple structure, high sensitivity and adaptability could be widely used velocity parameter measurement.
