Photosensitivity

Vedclass · Answer

(B) The $Vidicon$ is a type of video camera tube that operates based on the principle of photoconductivity (photosensitivity).It uses a photoconductive target that changes its electrical resistance when exposed to light.An electron beam scans the target,and the variation in conductivity creates a charge pattern corresponding to the image,which is then converted into an electrical signal.

On which principle does the $Vidicon$ work?
