Our imager is about seven times more powerful than a conventional lens of the same depth” - Eric Tremblay, the first author on an Applied Optics paper published February 1, 2007, and an electrical and computer engineering Ph.D. candidate at UCSD’s Jacobs School of Engineering. Eric is working with Joseph Ford, a professor of electrical and computer engineering at the Jacobs School who leads the camera project within UCSD’s Photonic Systems Integration Lab. Ford is also affiliated with the UCSD division of the California Institute of Telecommunications and Information Technology, Calit2.
