Abstract
The present invention relates to a micro dual orthogonal right angle prism array panel capable of homoaxial imaging. By orthogonally arranging two right angle prisms, the incident light and the outgoing light are aligned in the same axial direction, allowing an object to be imaged at a certain distance from the prism array panel, thus forming a floating image. The present invention has characteristics of short-distance imaging with no image distortion, significantly reducing the size of projection devices. Moreover, the present invention can be configured with a flat panel display; by moving it reciprocally and displaying sectional images of an three-dimensional object during moving, a floating volumetric projection image in midair can be formed and thus create a three-dimensional projection.
Claims10
A prism array panel capable of homoaxial imaging, comprising:
- a plurality of first units, each of the first units having:
- a first prism, including a first incident surface, a first incident reflective surface, a first outgoing reflective surface, and a first exiting surface, wherein the first incident reflective surface and the first outgoing reflective surface are adjacent to each other to form a first right angle, while the first incident surface and the first exiting surface are formed on the opposite sides of the first right angle;
- and
- a second prism, including a second incident surface, a second incident reflective surface, a second outgoing reflective surface, and a second exiting surface, wherein the second incident reflective surface and the second outgoing reflective surface are adjacent to each other to form a second right angle, while the second incident surface and the second exiting surface are formed on the opposite sides of the second right angle;
- wherein the first prism and the second prism are connected orthogonally, with the first exiting surface corresponding to the second incident surface;
- and when an incident light enters from the first incident surface, it can emit homoaxially from the second exiting surface;
- and
- the plurality of the first units are arranged in an array with intervals or adjacent to form the prism array panel.
