Laser shearography using real-time electronic image processing has been in use for the inspection of aircraft structures since 1988 when it was introduced on the USAF B-2 program for the nondestructive evaluation (NDE) of honeycomb control surfaces. Since that time, shearography techniques for NDE of aerospace structures have matured considerably to provide both more repeatable and quantifiable results but also broaden the applications considerably. This paper explores shearography techniques currently in use and applications on aerospace vehicles.
