What device may be used in the television system instead of Vidicon or Plumbicon tubes?

The charge-coupled device (CCD) is an important imaging technology utilized in television systems as an alternative to traditional video camera tubes like Vidicon or Plumbicon. CCDs are semiconductor devices that convert light into an electrical charge, allowing for high-quality image capture with greater sensitivity and lower noise levels, especially in low-light conditions.

CCDs are also known for their ability to produce consistent and reliable image quality over time, which makes them suitable for a wide range of applications, including professional video cameras and digital imaging systems. Their efficiency in capturing images is a significant enhancement over older tube-based systems, leading to the widespread adoption of CCD technology in modern video equipment.

While cathode ray tubes (CRTs) represent older display technology and are not used as image sensors, devices like direct digital sensors and flat panel detectors serve different roles in image capture and display systems. However, CCDs specifically address the imaging requirements that are essential for television systems.
