Persistence of vision is a sine qua non for any television system in which the scene being televised is analysed and the associated reconstituted image is synthesised by scanning beams of light or electrons. It is necessary that the rate at which the images are presented to an observer be sufficient to ensure that they do not appear as a series of still images. The rate must be such that the eye-brain combination fuses the individual images into a fiickerless picture.
