Inline Coherent Imaging Technology Goes Global

Recently, Queen's startup company Laser Depth Dynamics (LDD) was purchased by IPG Photonics Corporation, the world leader in high-performance fibre lasers and amplifiers. LDD was founded in Kingston 2012 by Paul Webster (Sc'06, PhD'13) and Roger Bowes (Sc'92), with the support of Prof. James Fraser, Queen's PARTEQ Innovations (now part of the Queen’s Office of Partnerships and Innovation). Dr. Webster, who is a graduate of Queen's Engineering Physics, developed the key LDD technology called Inline Coherent Imaging (ICI) during his PhD under the supervision of Prof. James Fraser in the Department of Physics, Engineering Physics & Astronomy. The ICI technology allows for direct measurement of weld penetration depth for laser welding. This is done using a near-infrared measurement beam to ensure high quality in real-time. IPG Photonics Corporation aims to incorporate LDD’s technology into its laser welding solutions to drive adoption of this advanced technology throughout manufacturing of metal parts.
