Dr. Simon Thibault received a BSc in physics engineering in 1994 and a MS in physics in 1995 from Laval University (Québec, Canada). He completed his PhD in optical system design in 1998 with the same University and after five years as head of the optical design department at the National Optical Institute (INO) in Québec. He joined ImmerVision (Montréal, Canada) in 2005 as principal optical designer and Director – Optical Division. He has authored and co-authored 12 patents and over 100 technical communications and papers for renowned optics conferences and journals. Simon is involved in several international conference program committees dealing with optics and is frequently invited as an expert speaker. He created the first ImmerVision panomorph lens design (IMV1-1/3) suitable for mass production, authored numerous scientific papers on the subject and is responsible for ImmerVision’s panomorph lens design certification program (CPOP). His interests and skills include wide angle optical imaging system design, lens design process, optimisation, optical testing, stray light and photometric/radiometric analysis of visible, near IR and IR optical systems. Simon is chair holder since 2008 of the new NSERC industrial research chair for lens design at Laval University.

Our main goal is therefore to increase the Kinect v2 field of view while keeping its main feature of depth measurements. A simple but effective solution consists in using a conversion lens to increase the ray collection angle before the rays enter the IR camera. Depth measurements remain possible from each pixel using TOF with the Kinect v2 modulated signal, provided the field of illumination matches the field of view. A trade-off has to be made between accuracy of depth measurement, optical performance and field of view/illumination enhancement. Therefore, we modified a Kinect v2 to characterize its optical performances and evaluate its relevancy for applications requiring accurate knowledge of the 3D surroundings.
A field of view improvement of the Kinect v2 and other similar TOF cameras could offer an alternative at minimal cost for depth measurements in machine vision, specifically in mobile robotics research where object detection and mapping tasks are frequently carried out.
