Flaws identified faster than in ultrasonic inspection. Holographic technique detects hidden "unbonds", and does not require elaborate provisions for suppression of vibrations. Laser-shearographic apparatus used to observe object while stress being applied. Shearographic image indicative of deflection caused by stress. Also used to inspect complexly contoured surfaces.
