Abstract
An optical system for 360.degree. image transfer in which spaced primary secondary hyperbolically surfaced mirrors are combined with a refractive lens system and are held in spaced relation by a transparent envelope having inner and outer surfaces generated from the near focal point of the primary mirror to avoid ray pass through distortion, and in which the mirrors are so spaced and concentrically arranged that the entrance pupil of the lens system coincides with the near focal point of the primary mirror, which is centrally apertured to form an aperture stop (diaphragm), and the near focal point of the secondary mirror approximates the apex of the primary mirror, the far focal points of the mirrors coinciding to form a confocal set of mirrors.
