Charge-Coupled Device (CCD) sensors are a type of image sensor used in digital cameras and imaging devices. By understanding how to calculate the size of an object as captured by a CCD sensor, one can make accurate measurements from images, enhancing the capabilities of fields ranging from astronomy to forensic science. The calculations involve considerations such as the lens focal length, the distance from the lens to the object, the size of the CCD, and the resolution of the CCD. The discipline associated with these concepts is Optics, a branch of Physics.

The understanding and ability to calculate the size of an object using CCDs has significantly contributed to technological advancements in numerous fields such as astronomy, medicine, and security. From capturing distant celestial bodies in space telescopes to detecting minute details in forensic or medical images, the application of CCDs and their associated calculations has proven to be revolutionary.
CCD sensors are used widely in digital cameras and imaging devices across numerous industries. Astronomers use CCDs in telescopes to measure light from distant stars and galaxies. In medicine, CCD cameras are used in microscopes and other imaging equipment to capture detailed images of cells and tissues. In security, CCD cameras are used in surveillance systems to monitor and record activities.
Willard S. Boyle and George E. Smith, who invented the CCD in 1969 while at Bell Labs, have made a profound contribution to this field. Their work revolutionized the field of imaging and won them the Nobel Prize in Physics in 2009.
Understanding how to calculate the size of an object as captured by a CCD sensor is crucial in many scientific and industrial applications. The invention of the CCD and the development of methods to optimize its use have led to significant advancements in imaging technology, improving our ability to explore, understand, and interact with the world around us.
