Abstract

An optical imaging system for compensating for the image elongation inherent in the transferring and fixing process without introducing unsharpness in the image wherein the original moves in the object space relative to an optical system. The optical system projects an image of the original onto a light sensitive element which moves relative to the optical system at a different speed than does the original, such that the ratio of the two speeds determines the desired shortening of the image. In order to prevent image unsharpness, the angle between the image plane and the light sensitive element is determined as a function of the desired shortening of the image. This angle must be such that a point on the light sensitive element passes through the image space in the same time it takes a point on the original to pass through the object space.
