Abstract

The flicker free cine projection system has a series of lenses(7) on a circular band(6) rotating about the optic axis. The film(1) moves in a similar circular track at the same angular rate as the lens carrier. This provides a smooth change from frame to frame without any flicker. The images are projected into the centre of the lens carrier from where they are deflected to the screen.
