Abstract

This paper describes a brief summary of applications of holographic interferometry to practical vibration study in Nagasaki Technical Institute of MHI. The applications of vibration mode measurement are concerned with steam turbine blades, compressor impeller, internal combustion engine, car body and car brake disk. The techniques of holography contained herein are (1) the time average method giving contour fringes of vibration amplitude,(2)the phase modulation method providing information on the relative phases of vibration, and(3)the double pulse method that offers the possibility of visualizing the vibration pattern of internal combustion engine in operating condition,and the transient vibration pattern of an object excited by impact force.
