Manufacturing Methods and Technology for Real-Time Ultrasonic Imaging.

Abstract

The breadboard of a real-time ultrasonic imaging system was constructed and demonstrated. The core of the breadboard RTUIS was a liquid surface holographic inspection system to which a number of digital features were added to give video monitoring, 3-D presentations of flaws, frame summing, decision making on defects, contrast enhancement, filtering and smoothing. RTUIS demonstrated its capability to locate flaws in composite and metallic structures ranging from thin graphite epoxy rings, to Viper launch tubes, to Viper rocket motor casings, to thick (5-inch) stainless steel weldments. Additional keywords: Acoustic imaging; nondestructive testing; contrast enhancement; filtering; smoothing; slit cameras. (Author)
