DESCRIPTION:Prof. Eric R. Fossum from the Thayer School of Engineering at 
 Dartmouth.\nThe Quanta Image Sensor (QIS) was conceived when contemplating
  shrinking pixel sizes and storage capacities\, and the steady increase in
  digital processing power. In the single-bit QIS\, the output of each fiel
 d is a binary bit plane\, where each bit represents the presence or absenc
 e of at least one photoelectron in a photodetector. A series of bit planes
  is generated through high speed readout\, and a kernel or “cubicle” o
 f bits (X\,Y\, t) is used to create a single output image pixel. The size 
 of the cubicle can be adjust post-acquisition to optimize image quality. T
 he specialized sub-diffraction-limit photodetectors in the QIS are referre
 d to as “jots” and a QIS may have a gigajot or more\, read out at 1000
  fps\, for a data rate exceeding 1Tb/s. Basically\, we are trying to count
  photons as they arrive at the sensor. Recent progress towards realizing t
 he QIS for commercial and scientific purposes will be discussed.  This in
 cludes investigation of a pump-gate jot device implemented in a 65nm proce
 ss\, power efficient readout electronics\, currently  less than 20pJ/b in
  0.18 um CMOS\, creating images from jot data with high dynamic range\, an
 d understanding the imaging characteristics of single-bit and multi-bit QI
 S devices\, such as the inherent and interesting film-like D-log(H) charac
 teristic. If successful\, the QIS will represent a major paradigm shift in
  image capture.\nBio: Eric R. Fossum is a Professor at the Thayer School o
 f Engineering at Dartmouth. His work on miniaturizing NASA interplanetary 
 spacecraft cameras at Caltech’s Jet Propulsion Laboratory in the early 1
 990’s led to his invention of the CMOS image sensor “camera-on-a-chip
 ” that has touched many here on Earth\, from every smartphone to automob
 iles and medicine\, from security and safety to art\, social media and pol
 itical change. Used in billions of cameras each year\, his technology has 
 launched a world-wide explosion in digital imaging and visual communicatio
 ns.\nHonors include induction into the National Inventors Hall of Fame and
  election to the National Academy of Engineering and the National Academy 
 of Inventors.  He received the NASA Exceptional Achievement Medal and is 
 a Fellow of the IEEE. He co-founded the International Image Sensor Society
  and served as its first President.\nA graduate of Trinity College and Yal
 e University\, Dr. Fossum taught at Columbia and then worked at JPL. He co
 -founded and led Photobit Corporation and later led MEMS-maker Siimpel. He
  joined Dartmouth in 2010\, where he teaches and continues research on ima
 ge sensors\, and is Director of the school’s Ph.D. Innovation Program. 
  He has published over 260 technical papers and holds over 150 U.S. patent
 s. He and his wife have a small hobby farm in New Hampshire and he enjoys 
 his time on his tractor.
