The most characteristic optical aberration in the rotating-prism non-intermittent cinematograph projector, the non-linearity of the image shift, can be eliminated by a suitable periodic variation of the direction of the illuminating beam. In addition to a description of this unusual method of optical correction, other aberrations of the image formation by the rotating prism are discussed, such as the prismatic astigmatism and the tangential and sagittal prismatic coma.
