Holographic examination of objects unprotected from vibrations
Abstract
Two procedures for facilitating holographic interferometry of objects which are not mounted in a vibration-free environment are investigated. The studied procedures involve stroboscopic illumination or use of the phase reference mirror method (for coupling of the object and reference waves). The theoretical bases of the procedures, which can be combined, are explained, and satisfactory experimental measurements were obtained.
