What is a CCD (charge-coupled device)?
A) a detector in which a small electric current is controlled by a bimetallic strip that expands and contracts in response to infrared radiation
B) an electronic filter to single out one wavelength or set of wavelengths for studying astronomical objects
C) a device in which an image from a photographic plate or film is transferred to a computer by moving static-electric charges directly into the computer memory in a manner similar to modern copying machines
D) an array of small, light-sensitive elements that can be used in place of photographic film to obtain and store a picture

Question

Quizplus · Accepted Answer

A CCD (charge-coupled device) is an array of small, light-sensitive elements that can be used in place of photographic film to obtain and store an image. When light hits the elements, it creates an electrical charge that can be read and converted into a digital signal to produce an image. CCDs are commonly used in digital cameras, telescopes, and other imaging devices.
