Abstract
An optical system for cameras and projectors includes a reflective convex mirror for a wide-angle view, for example, a sector of one fourth of a sphere to obtain a view of 180.degree.. The optical system further includes a front face reflecting mirror to change the optical path 90.degree., a first focusing lens, a fiber optic bundle and a second focusing lens. The fiber optic bundle has one face in the form of an annulus or sector of an annulus and the opposite face of rectangular shape so that an annular shaped image may be converted into a non-distorted image of rectangular form.
