The difference between virtual reality VR and holographic projection 3D

The difference between virtual reality VR and holographic projection 3D is: different viewing, different principles, and different requirements.

1. Viewing is different

(1) Virtual reality VR: Virtual reality VR requires auxiliary equipment for viewing.

(2) Holographic projection 3D: You can directly watch holographic projection 3D without auxiliary equipment.

2. Different principles

(1) Virtual reality VR: The principle of virtual reality VR is to use the grating principle for projection imaging to reproduce the true three-dimensional image of the object.

(2) Holographic projection 3D: The principle of holographic projection 3D is to use the principles of interference and diffraction to record and reproduce the true three-dimensional image of the object.

3. Different requirements

(1) Virtual reality VR: Virtual reality VR has certain requirements for viewing angle and distance.

(2) Holographic projection 3D: Holographic projection 3D has no requirements on viewing angle and distance.
