Dr William Cassarly, senior scientist of illumination engineering in the Optical Solutions Group at Synopsys, a company specialising in software and IP for semiconductor design, verification and manufacturing, has been promoted to Fellow by the Society of Photographic Instrumentation Engineers (SPIE).

Each year SPIE recognises distinguished individuals in the field of optics and optoelectronics through its Fellows programme. The promotion recognises Dr Cassarly's technical achievements in illumination system optimisation as well as his contributions to optics education.

Photonics West in San Francisco acknowledged 67 new Fellows who, according to SPIE, 'are honoured for their technical achievements, and for their service to the general optics community and to SPIE in particular.'

'Bill Cassarly has been a key contributor to the advancement of computer-aided illumination engineering, particularly in the development of practical and effective optimisation capabilities for illumination systems,' said George Bayz, vice president and general manager of the Optical Solutions Group at Synopsys. 'In addition, he has helped foster the next generation of illumination engineers by developing and teaching introductory and advanced design courses at SPIE meetings since 1999. We congratulate Bill on his achievements.'

Throughout his career, Dr Cassarly has worked extensively in the areas of illumination modelling, design and optimisation. He has contributed to major feature developments in LightTools illumination design software and to illumination engineering consulting projects for a range of applications. Systems he has designed include fibre optic headlights, compound parabolic concentrators, theater projection illuminators, room lighting, LED optics and UV systems.

In addition to presenting illumination courses, Dr Cassarly has authored numerous papers for SPIE meetings, served on programme committees for non-imaging conferences at SPIE's Photonics West and Optics and Photonics meetings, and co-authored a chapter on illumination engineering in the Optical Society of America's Handbook of Optics.
