Willard S. Boyle

Willard Sterling Boyle. 1924 – 2011 ) He was a co-inventor physicist for the CCD, a sensor used in digital still cameras. For this same invention, he was awarded the Nobel Prize for Physics in 2009 , along with George E. Smith and Charles K. Kao .

Biographical synthesis

Born in Amherst, Canada on August 19 , 1924 .


Boyle and Smith were awarded for inventing a “semiconductor image circuit, the CCD sensor” (charge coupled device), which is part, among others, of digital photographic machines, the institution reported.

The CCD is the “electronic eye of the digital camera” and determines its resolution. Also found in fax and scanner machines . Its discovery was also important for astronomy. “Without the CCD we would not have been able to see the amazing images of space taken by the Hubble Space Telescope,” says an Academy statement.

Boyle and Smith created the CCD chip. When light falls on its surface, electrical charges accumulate there. This can be read electronically and transformed into measurements and stored. The more intense the light that hits, the stronger the resulting signal. In this way, in a fraction of a second, a scene can be translated into clarity values. The digital cameras Modern chips have more than ten million fields, which are read in a split second. This technique practically replaced chemical photography, which is about 150 years old, in a few years.


He died on 7 of maypole of 2011 , at 86 years old.
