Physicist to discuss science of cell phone cameras

Talk is free and open to the public

Christopher Dainty

Tiny cameras in cell phones don’t work by magic. The pursuit of ever-smaller cameras requires scaled-down optical systems that can affect image quality.

Distinguished physicist Christopher Dainty will visit Rochester Institute of Technology for a talk about ideal imaging detectors and limitations of imaging systems in cell phones.

Dainty, professor at University College London Institute of Ophthalmology, will present “Imaging Science and Cell-Phone Cameras” at 6 p.m. on May 6 in the Carlson Auditorium in the Chester F. Carlson Center for Imaging Science. The talk is free and open to the public.

“Every optics student knows that bigger optical systems have the potential to form higher resolution and higher signal-to-noise images, yet market pressures drive cell phone cameras to be smaller and smaller,” Dainty said. “I shall discuss some of the fundamental limits of imaging systems that affect image quality in small cameras.”

Dainty is a fellow and past president of the Optical Society of America, SPIE (an international professional society for optics and photonics technology), the Institute of Physics and the European Optical Society. His research explores optical imaging, scattering and propagation, especially related to imaging and metrology and the eye.

The RIT SPIE/OSA Student Chapter is sponsoring the lecture.
