Abstract: The present invention relates to a device to generate, starting from a stationary slit, an image of this slit which scans in its transverse direction, comprising a light source arranged in such a way in front of this slit, that the principal rays through the slit are parallel to the optical axis of the device, and a straight, equilateral, transmitting polygonal cylinder located behind the slit which is arranged so as to rotate about its axis of symmetry parallel to the longitudinal direction of the slit, and a system of lenses arranged between the said polygonal cylinder and the image.

Abstract: The present invention relates to a device to produce, starting from a slit scanned in its transverse direction, alternately two slits scanned at a certain angle to each other in their transverse directions in the same image plane. Starting with the slit scanned in its transverse direction, the device in accordance with the invention produces two slits scanned at a certain angle to each other in their transverse directions in the same image plane. This slit scanned in its transverse direction may be generated, for example, by means of a device comprising a straight, equilateral, transmitting polygonal cylinder placed behind a stationary slit which is arranged to rotate about its axis of symmetry parallel to the longitudinal direction of the slit. The two slits scanning in the same image plane at a certain angle to each other in their transverse directions are generated by means of the device built in accordance with the principles of the present invention by dividing the light alternately in time between two alternative ray paths. The device including a rotating glass disk with reflecting areas being used for the division and the ray paths have such optical characteristics that the timing of the scanning slits is not affected by wobble in the bearings of the rotating glass disk.
