image dissector

An image dissector is a type of early television camera tube that converts visual images into electrical signals for broadcast. It uses a scanning process where a focused electron beam rapidly moves across a photosensitive surface illuminated by the scene. As the beam scans, it detects the light intensity at each point, generating a corresponding electrical signal that reproduces the image. This technology was essential in early televised images, transforming visual information into electronic form for transmission and display, laying the groundwork for modern imaging and television technology.
