Abstract	Korea Air force standard NDE coupons which are practical structures used in real aircraft construction were inspected using full-field pulse-echo ultrasonic propagation imaging (FF PE UPI) system. The Korea Air force standard NDE coupons consist of a laminated carbon fiber reinforced plastic (CFRP) step and a CFRP skin/honeycomb sandwich, an aluminum honeycomb sandwich, a bonded aluminum-aluminum coupon, an aircraft magnesium fin including various defects. The FF PE UPI system inspects based on combined generation and sensing laser beams for generating and sensing pulse-echo ultrasound and two-axis transition stage for raster scan. In order to visualize various defects of the coupons, pulse-echo ultrasonic wave propagation imaging algorithm is used after scanning the coupons.
