Description
At the heart of every camera, is the image sensor that converts light into electrical signals. The CMOS image sensor, invented by the speaker and his group at the NASA Jet Propulsion Laboratory (Caltech), is now used in billions of cameras each year, including smartphones, webcams, automotive cameras, swallowable pill cameras and many other applications, and billions of pictures are uploaded every day around the world via the internet.
In the first part of this talk, the basic principles of image sensors from light to digital signals will be discussed, along with the short story of the CMOS image sensor invention and commercialization by our spinoff company Photobit. In the second part of the talk, the Quanta Image Sensor (QIS), a possible paradigm shift in solid-state image sensors, will be presented. Conceptually, the QIS counts photons one at a time using small pixels with low full-well capacity and single-photoelectron sensitivity. This binary data is collected and transformed into gray scale images by post-acquisition digital image processing. In recent years, the QIS has moved from concept to experimental devices at Dartmouth.
The lecture will be followed by the screening of the movie "Back to the Future".
A cocktail reception will take place prior to the keynote lecture from 5:00 p.m.
Nannie services are available for children from 3 to 8 years old. To register click here.

Eric Fossum
Dr. Eric Fossum is a Professor at the Thayer School of Engineering at Dartmouth and Director of the School’s Ph.D. Innovation Program. He is a semiconductor device physicist and engineer specializing in image sensor He is best known for the invention of the CMOS image sensor now used in billions of cameras. He was inducted into the US National Inventors Hall of Fame in 2011 and is a member of the US National Academy of Engineering and a Charter Fellow of the National Academy of Inventors. In 2017, it was announced he would receive the Queen Elizabeth Prize for Engineering, the highest global prize in engineering.
He received his B.S. in Physics and Engineering from Trinity College, Connecticut USA in 1979, his Ph.D. from Yale University in 1984 and became an EE faculty member at Columbia University. In 1990, he was recruited to the NASA Jet Propulsion Laboratory at Caltech where he managed JPL’s image sensor and focal-plane technology R&D and invented the CMOS image sensor. He then co-founded and led Photobit Corporation to commercialize the technology. Photobit was acquired by Micron in 2001. He later served as CEO of Siimpel Corporation to commercialize MEMS auto-focus actuators for camera phones. He worked with Samsung Electronics before joining Dartmouth in 2010. He has published over 290 technical papers and holds over 160 US patents. Dr. Fossum co-founded the International Image Sensor Society (IISS) and served as first President.
