Performance and Analysis of Feature Tracking Approaches in Laser Speckle Instrumentation

Autor: Thomas Charrett, Ralph Tatam

Publikováno v: Sensors, Vol 19, Iss 10, p 2389 (2019)

This paper investigates the application of feature tracking algorithms as an alternative data processing method for laser speckle instrumentation. The approach is capable of determining both the speckle pattern translation and rotation and can theref

In-process range-resolved interferometric (RRI) 3D layer height measurements for wire+ arc additive manufacturing (WAAM)

Autor: Ralph Tatam, Thomas Charrett, Thomas Kissinger, Jonathan Mark Hallam

In this work a range resolved interferometry (RRI) instrument for absolute distance measurements is integrated into a wire + arc additive manufacturing (WAAM) system to provide in-process monitoring of layer height, and prospects for volume and profi
