Abstract
Ultrasonic imaging using phased arrays is a crucial non-destructive test. In this paper, a phased array ultrasonic system is designed and implemented. It is implemented using integrated electronic circuits which results in higher image quality and lower noise, lower cost, lower weight and smaller dimensions with respect to current systems. The implemented system supports all phased array probes with standard connector up to 16 elements and its sampling rate is 40MHz and is capable of upgrading to higher number of elements and sampling frequencies. Imaging is implemented using total focusing method which results in higher quality images with lower noise in comparison to regular phased array images. Portability, development to use in all non-destructive imaging tests and a lower price in comparison to current imaging systems, are major features of this product. The experimental results demonstrate that the system easily distinguishes between three holes with 0.8mm, 0.6mm and 0.3mm diameter.
