Simplified Phased Array Ultrasonic Flaw Detection and Imaging System Model

A simplified model of a phased array ultrasonic flaw detection and imaging system. The system currently supports simulation of imaging results for three different acoustic beam types, making it ideal for understanding ultrasonic flaw detection principles through practical implementation.

This model utilizes advanced phased array technology where beam forming is controlled through precise timing delays applied to individual transducer elements. The code implementation includes dynamic focus control algorithms that adjust phase shifts to steer and focus ultrasonic beams, generating accurate imaging results. Multiple imaging modes have been integrated to simulate real-world flaw detection scenarios, including linear scanning, sector scanning, and focused beam inspections.

Through this model, users can gain deeper insights into ultrasonic flaw detection mechanisms. The system allows parameter adjustment of acoustic beams (such as frequency, angle, and focus depth) to observe defects or structural features in various materials. The imaging algorithm processes echo signals using signal processing techniques like time-of-flight calculation and amplitude thresholding to characterize material properties and defect influences.

Comprehensive documentation and tutorials are provided to facilitate model usage. Users can learn parameter configuration methods, image interpretation techniques, and optimization strategies for flaw detection performance. The code structure includes modular functions for beam forming, signal processing, and image reconstruction, with commented sections explaining key algorithms like delay-and-sum beamforming and image interpolation methods.

This model serves as an educational tool for understanding ultrasonic flaw detection principles while providing practical support for research and industrial applications through its customizable simulation environment.
