A NEED EXISTS FOR AN NDI TECHNIQUE THAT CAN SCAN LARGE AREAS OF COMMERCIAL OR MILITARY AIRCRAFT TO DETERMINE WHETHER THAT AIRCRAFT CAN BE RETURNED TO SERVICE OR SHOULD BE PLACED INTO MAINTENANCE. THE REQUIREMENTS FOR THIS LARGE-AREA SCANNING TECHNIQUE ARE SPEED, SIMPLE OPERATION BY A FEW TECHNICIANS, EASILY INTERPRETED AND ARCHIVED DATA, AND DETECTION OF DELAMINATIONS, DISBOND, CRACKS, AND IMPACT DAMAGE. TWO NDI TECHNIQUES THAT PROMISE TO SATISFY THE REQUIREMENTS ARE SHEAROGRAPHY AND PULSED INFRARED THERMOGRAPHY. EACH OF THE TWO TECHNIQUES IS DESCRIBED AND DISCUSSED IN TERMS OF THESE REQUIREMENTS.
