George E. Smith, who won the Nobel Prize in Physics for inventing a revolutionary imaging device that has not only allowed scientists to see the universe more clearly but has also made it possible for hundreds of millions of people to record every birthday and vacation for posterity, died on Wednesday at his home in Barnegat Township, N.J. He was 95.

His death was confirmed by his daughter Lauren Lanning.

It was while he was working at Bell Laboratories in 1969 that Dr. Smith and a colleague, Willard S. Boyle, came up with the idea for what is known as the charge-coupled device, or CCD — a technology that is an essential component of nearly every telescope, medical scanner, photocopier and digital camera in use today.

Their work helped build “the foundation to our modern information society,” Gunnar Oquist, the Nobel academy’s secretary general, said when it was announced that Dr. Smith and Dr. Boyle would share the 2009 prize for physics. (They split the award with Charles K. Kao, who was recognized for work that resulted in the development of fiber-optic cables.)

Dr. Smith and Dr. Boyle had been trying to create better memory storage for computers when the idea for the CCD arose. They thought the photoelectric effect — which Einstein had explained, an explanation that won him a 1921 Nobel Prize — might offer a solution.

The photoelectric phenomenon occurs when electromagnetic radiation, such as light, hits a metal surface, dislodging electrons from atoms and causing a current to flow through the metal. The device that Dr. Smith and Dr. Boyle created employs rows of tiny capacitors to store and transfer the electrical charge — essentially capturing light — and uses the information to construct an image.
