Which is a common use for a Charged Coupled Device (CCD)?

A Charged Coupled Device, or CCD, is predominantly utilized for image capture. This technology is fundamental in various imaging applications, particularly in digital cameras, astronomy, and video recording. The CCD works by converting light into electronic signals, allowing for the creation of high-resolution images with excellent sensitivity and low noise.

In the context of its operation, incoming photons hit the semiconductor material of the CCD, generating charge carriers. These charges are then shifted across the device and read out in a way that creates a digital representation of the captured image. This capability makes CCDs highly suitable for tasks that require precise and quality image acquisition.

Other options, such as power transmission, data storage, and signal processing, do not align with the inherent purpose of CCD technology. Power transmission involves electrical systems designed to move electricity from one point to another. Data storage pertains to saving information in formats suitable for retrieval, while signal processing covers operations performed on signals to modify or improve them; none of these directly relate to the core functionality of CCDs in image capturing.
