PhotoTubes
In this device, it emits negative charge carriers i.e, electrons from a photosensitive negative charged cathode when it stike by visible or UV radiations. Electrons e– flow through a vacuum to an anode to produce current which is proportional to radiation intensity.
Photodetector
A photo is nothing but light. A detector is nothing but a device that detects something. Therefore, we can directly conclude that a photodetector can be defined as a device that is used to detect light radiations by absorption.
