This citation summarizes a one-page announcement of technology available for utilization. Holographic detection of unbonded or delaminated surfaces of materials and structures is improved by using heluim instead of air in the vacuum test chamber. Wider-spaced interference fringes more clearly outline the flaws. ...FOR ADDITIONAL INFORMATION: Contact: Director, Technology Trassfer Division, P.O. Box 8757, BWI Airport, MD 21240.
