Smaller CCDs gain imaging speed

摘要

Detectors underlie the technology of many types of equipment, from commonplace systems such as fax machines to much more-complex devices such as space telescopes. In this new series, contributing editor Eric Lerner explains how detectors work, examines their key applications, and reveals how these devices hold up against competing technology. This month, he looks at why charge-coupled devices have become key components in a variety of diverse imaging applications.
