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.

Prof. Martin Duncan's Retirement

Professor Martin Duncan retired from the Department in December 2017 and a party was held at the University in celebration of his long and distinguished career at Queen's. Dr. Duncan received his PhD in Astronomy from the University of Texas at Austin in 1980. From 1979 to 1982 he was a postdoctoral fellow at Cornell University. He returned to the University of Toronto as an Assistant Professor from 1982 to 1987 and spent a year at the University of California at Santa Cruz in 1987-1988 as an Assistant Professor. He arrived at Queen’s University as an Associate Professor in 1988, was promoted to Professor in 1993 and retired in December 2017.
