The present work evaluates the application of artificial neural networks for pattern recognition of ultrasonic signals using pulse-echo and TOFD (Time of Flight Diffraction) techniques in weld beads.
Abstract: Interference and diffraction of light are elementary topics in optics. The aim of the work presented here is to develop an accurate and cheap optical-system simulation software that provides ...
Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

Decode a set of focused transmit ultrasound beams into the "complete data set", indexed by individual transmit elements and receive channels. Algorithms are provided for both "phased" and "walking" ...
Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
===== MatLab functions and scripts for processing raw MED X-ray diffraction files (Tailored to X17B2 and 6-BM-B) This repository contains various MatLab functions and scripts I have developed to deal ...
What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...
