1. An omnidirectional imaging apparatus for sensing an image of a substantially hemispherical scene from a single viewpoint, comprising:

  • (a) a truncated convex substantially paraboloid-shaped reflector positioned to orthographically reflect an image of said substantially hemispherical scene, said paraboloidal reflector having a focus coincident with said single viewpoint of said omnidirectional imaging apparatus, including said reflector;

    (b) telecentric means, optically coupled to said reflector, for substantially filtering out principal rays of electromagnetic radiation which are not orthographically reflected by said reflector; and

    (c) an image sensor positioned to receive said filtered orthographic reflection of said image.
