ABSTRACT:
A device for mechanically moving the instantaneous image spot of a cathode ray tube at right angles to the scan direction with respect to a photographic film on which the total image is recorded by vibrating a portion of the imaging system so that the spot moves at a higher relative speed at right angles than at the normal scan direction so that the information on one scan line occupies all, or very nearly all, of the space between the scan lines as they are projected on the film.
