Paper Abstract

This device utilizes single mode polarization maintaining optical fibers to generate the pair of laser beams required by diffraction moire interferometry. Design of the device permits extremely rapid and convenient setup for measurement of in-plane displacement distributions on the surfaces of specimens. The device, applications, and typical data are described.
