ABSTRACT:
Anamorphotic optical system transmitting an image while deforming it in one direction and leaving it undeformed in a substantially perpendicular direction. It comprises a main fibre-optical image guide (210) cemented to an exit face (213, 213.sub.2) of at least one beveled supplementary fibre-optical guide (220, 220.sub.2), the axes of the optical fibres of the two guides (210, 213, 213.sub.2) being not parallel to one another. Thus, the magnification of the image is not uniform in the direction of deformation. The transmitted image has either at least two parts each representing a different magnification, or a progressive deformation in the direction of the deformation.
