PINHOLE ARRAY AND DISPLAY DEVICE USING SAME

摘要

Two pieces of elliptic semi-sphere surfaces, each forming a pinhole at the zenith thereof and also forming a reflection mirror on an inside thereof are stuck onto each other, with facing the interior surfaces thereof, respectively. A light ray entering therein from one of the pinholes, after being reflected between the elliptic semi-sphere surfaces facing to each other, emits from the pinhole on opposite side at an angle plane symmetric to the incident angle. Disposing the elliptic semi-sphere surfaces facing to each other, aligning on a plane, by plural numbers thereof, there is built up a pinhole array. Plural numbers of light rays reflecting on and/or emitting from a display object, which is disposed on one side of the pinhole array, after passing through the plural numbers of pinholes of the pinhole array, form an image at a position plane symmetric thereto, on the opposite side of the pinhole array.

主权项

1. A pinhole array, comprising:
plural numbers of entrance pinholes, each of which is configured to capture a light ray therein; plural numbers of exit pinholes, each of which is configured to emit the light ray therefrom; and plural numbers of pinhole reflectors, in each of which a pair of an entrance pinhole and an exit pinhole are formed to face to each other, and each of which is configured to emit the light ray entering therein from said entrance pinhole, after reflecting at least two (2) times therein, wherein an image is formed by the light rays emitting from said plural numbers of exit pinholes.
