Problems solved by technology

[0004] In this solution, a lens is set between the projector and the holographic projection pyramid, and the image is zoomed by adjusting the height of the fixed layer of the lens. However, the lens is spherical, and the image from the projector is under the action of the lens. will be distorted, and the outline will appear blurred

Abstract

The invention relates to the field of holographic projection, in particular to a distortion-proof 3D holographic projection apparatus. The projection apparatus comprises a positioning apparatus, a projector fixing layer and a lens fixing layer, wherein the positioning apparatus comprises a base; telescopic rods are arranged on four corners of the base; a pyramid receiver is mounted on the base; the lens fixing layer is arranged in parallel at the upper end of the base; the projector fixing layer is arranged in parallel at the upper end of the lens fixing layer; a mounting hole is formed in the projector fixing layer; a projector is arranged on the mounting hole; a placement hole is formed in the lens fixing layer; a lens is fixed on the placement hole; the mounting hole and the placement hole are coaxial; a fidelity layer is arranged between the lens fixing layer and the base; a fixing hole is formed in the fidelity layer; and a parallel lens enabling light rays to be emitted in parallel is arranged on the fixing hole. According to the projection apparatus, a zoomed image is clear in contour and low in distortion rate.

Description

technical field [0001] The invention relates to the field of holographic projection, in particular to an anti-distortion 3D holographic projection device. Background technique [0002] Holographic projection technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional images of objects. The first step is to use the principle of interference to record the light wave information of the object, which is the shooting process: the holographic projection shooting process of the object forms a diffuse object beam under laser irradiation; the other part of the laser beam is used as a reference beam to shoot onto the holographic film , superimposed with the object beam to generate interference, and convert the phase and amplitude of each point on the object light wave into a spatially varying intensity, so that all information of the object light wave can be recorded b...
