Review of Development and Application for Laser Doppler Vibrometer

Abstract

Take Germany Polytec company, America OptoMET company and domestic Sunny company as examples, this paper introduces the products of single point laser vibrometer, multipoint laser vibrometer, high speed laser vibrometer, remote laser vibrometer, optical fiber laser vibrometer, micro laser vibrometer, scanning laser vibrometer, robot laser vibrometer, 3D laser vibrometer, etc., and their typical applications of vibration measurement which in rotating machinery, biomedical engineering, acoustic quality testing, MEMS, etc. Aiming at the problems existing in the products, the research and application development ideas are pointed out.
