The charged-couple device: changing how far we can see

Bryson Masse

Algonquin College Journalism Program

Today it’s taken for granted that we can document our life using photos and videos. But these quick, effortless snapshots would not have been possible without Willard Boyle’s invention of the charged-couple device, or CCD. The CCD was invented during a brainstorming session between him and his colleague, George Smith, at New Jersey’s Bell Labs. The device is a grid of semiconductors that can be used to collect photons and convert them to electricity, much like solar panels.

By 1969, when Boyle and Smith invented the CCD, Boyle had many incredible experiences under his belt. He was a World War II veteran, and was part of the team that invented the continuously operating ruby laser. He also helped select landing sites for the Apollo moon missions. Boyle was the executive director of device development at Bell Labs when he was challenged by his boss Jack Morton, to invent a new kind of computer memory. This project developed into the technology we know as the CCD.

The implications for imagery caught on with incredible speed and made a huge difference in astrophotography, spy warfare and spectroscopy. This made the traditional process of photograph development obsolete, meaning that devices could be lighter, faster and didn’t need disposable film. The majestic photos from the Hubble space telescope, created by the collection of far away light in a CCD, permanently impacted our view of the universe.

Willard Boyle was inducted into the Canadian Science and Engineering Hall of Fame in 2005; he was recognized by a Nobel Prize in 2009.
