Charge-coupled Device

A charge-coupled device (CCD), abbreviated as CCD, is a leading sensor technology used for capturing images in a variety of applications. A CCD sensor consists of an array of semiconductor detectors arranged either in rows or in a matrix. Each individual detector in a CCD sensor acts as a pixel that measures the brightness and color of a specific point in the image.

How a CCD sensor works

When light falls on the surface of a CCD sensor, it generates electrons in the semiconductor detectors. These electrons are then captured by electrical charges and passed from pixel to pixel in a process called “charge-coupling” before finally being read out and converted into an image. This method enables precise and high-resolution image capture, which is used in many areas such as photography, medicine, astronomy and industrial image processing.

Areas of application for CCD sensors

CCD sensors are used in a wide range of applications, including

  • Digital cameras: for high-resolution images and videos.
  • Medical imaging: To create precise diagnostic images in areas such as radiology and endoscopy.
  • Astronomy: For capturing images of space and astronomical objects.
  • Machine vision: For quality control, inspection and automated process control in manufacturing.
