RECEIVING OPTICAL SYSTEM FOR PANORAMIC OPTOELECTRONIC DEVICE Russian patent published in 2011 - IPC G02B17/08 G02B13/06 

FIELD: physics.

SUBSTANCE: system for panoramic optoelectronic device comprises an optical paranomic unit 2 and a multi-element radiation receiver 10 placed at the rear focal plane 11 thereof, the two components being axially symmetric and arranged in series along the optical axis 1. The optical panoramic unit 2 is in form of a first convex refracting surface 3 on which the information stream 4 is directed along the main beam 5, a second convex reflecting surface 6 superimposed with an axially symmetric aperture diaphragm 7, a third concave reflecting surface 8 and a fourth refracting surface 9. The first convex refracting surface 3 and third concave reflecting surface 8 are semitransparent, have identical clear apertures and surface form and are completely superimposed with each other.

EFFECT: high field angle, limiting the aperture ratio, high resolution, smaller size due to smaller diameter of the first convex refracting surface.
