Title: Cinematic film projector

Abstract: In a cinematic film projector a light source projects light through a single, non-centric light transparent transmission window formed in a rotary shutter, and through an image window and an image of a film which passes step by step past the image window for projection by a projector lens onto a cinema screen. In order to obtain a higher image frequency, the rotary shutter is made of light transparent material that is coated so that light passes through only its single light transmission window. Thereby the rotary speed of the rotary shutter can be significantly increased.
