| 摘要 |
<p>The invention relates to an optical device (40) for obtaining, with a single acquisition, a hyper-hemispheric field of view, which can be applied to an optical system (20) for obtaining a hyper-hemispheric image, comprising a retro-reflector (3) with an outer convex spherical surface (1) and an image sensor (18) for digital processing the field of view; the optical device (40) comprises an optical element (6) which is fixable to the retro-reflector (3) in correspondence with the outer convex spherical surface (1); the optical element (6) is able to capture the rays (16, 17) coming from an object to shoot and is able to transmit said rays to the image sensor (18). The invention also relates to an optical system (20) comprising said optical device (40), an apparatus for shooting images and an apparatus for projecting images comprising said optical system (20).</p> |
