| 摘要 |
An imaging apparatus for sensing an image of a scene from a substantially single viewpoint, which includes a truncated, substantially paraboloid-shaped reflector positioned to orthographically reflect principal rays of electromagnetic radiation radiating from the scene, the paraboloid-shaped reflector having a focus coincident with the single viewpoint of the imaging apparatus, including the paraboloid-shaped reflector. The imaging apparatus also includes telecentric means, optically coupled to the paraboloid-shaped reflector, for substantially filtering out principal rays of electromagnetic radiation which are not orthographically reflected by the paraboloid-shaped reflector. The imaging apparatus also includes one or more image sensors positioned to receive the orthographically reflected principal rays of electromagnetic radiation from the paraboloid-shaped reflector, thereby sensing the image of the scene. |
