Pulsed bipolar imager

Carver Mead, Tobi Delbruck and Nick Mascarenhas at Synaptics in 1997. Taken with the first functional pulsed bipolar imager, after a long night of detective work--hence the Sherlock Holmes shirt that I'm wearing.

Some early progress in this project was described in this paper:

The whole story from my view may follow later. The whole story of Carverland/Synaptics/Foveon has been told by George Gilder in his book "The Silicon Eye" (2005).
