Abstract:
1. An optical imaging apparatus comprising a flat plate-shaped light-controlling panel for forming a real image of an object at a position plane-symmetric to the object with respect to the light-controlling panel as a central plane, the light-controlling panel having numerous light-reflecting elements disposed side by side, each of the light-reflecting elements allowing light from the object to pass therethrough by reflecting the light at a first reflective surface and further reflecting the light at a second reflective surface, the second reflective surface being disposed on a level different from that of the first reflective surface while being paired with the first reflective surface, and being in a crossed arrangement with respect to the first reflective surface when viewed from thereabove, wherein the light-controlling panel is divided to comprise a plurality of segment light-controlling panels in which the first reflective surfaces and the second reflective surfaces included are parallel, respectively, and wherein centerlines of the respective segment light-controlling panels when viewed from thereabove intersect at one point on the light-controlling panel, and further wherein bisectors which bisect crossing angles between the first reflective surfaces and the second reflective surfaces of the light-reflecting elements existing on the centerlines coincide with the centerlines when viewed from thereabove.
