Description

Naked eye 4D holographic image device

Technical Field

The utility model relates to the technical field of imaging equipment, in particular to a naked eye 4D holographic imaging device.

Background

Existing mainstream holographic imaging techniques can be largely divided into two types:

1. and (5) plane rotation type. The technology mainly utilizes the persistence of vision of human eyes, uses a linear LED luminous element to rotate at high speed in a plane so as to realize the display in a certain plane, and basically, the display technology still displays the content in a two-dimensional plane, does not have depth display capability, and the visual effects of different angles are complete and the same as those of a plane display. There is no true "holographic" meaning.

2. Pyramid reflection type. The technology uses a reflecting mirror with a quadrangular pyramid structure, reflects a specially manufactured image to the periphery of a pyramid through a screen facing the tip of the quadrangular pyramid, and can realize the display effect of displaying four directions of an object respectively in four directions opposite to the pyramid. This display technique is superior to the former technique in terms of "holography", but has a disadvantage in that the corresponding contents can be displayed only in fixed 4 directions perpendicular to each other, and an ideal display effect (e.g., 45 deg.) cannot be achieved at any angle.

The above-mentioned holographic techniques have limitations and cannot be called true holographic techniques.
