Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers. A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen.

They had made modifications to Jenkins' patented Phantoscope, which cast images via film and electric light onto a wall or screen. The Vitascope is a large electrically-powered projector that uses light to cast images. The images being cast are originally taken by a kinetoscope mechanism onto gelatin film. Using an intermittent mechanism, the film negatives produced up to fifty frames per second. The shutter opens and closes to re

Paul at Finsbury Technical College on February 20, 1896. The use of Paul's Theatrograph in music halls up and down the country popularised early cinema in Britain. It was first revealed to the public at the Egyptian Hall in Piccadilly, London.
