Abstract

A projection moire interferometer is presented which was developed to study rotating vibrating objects such as turbine blade assemblies. Three methods of moire interferometry were used in this study: pulsed; time-average; and real time. Real-time moire interferometry used in conjunction with image derotation and strobe techniques is shown to be a viable method of studying traveling wave modes on a rotating disk.
