What's The Difference Between 3D For The Naked Eye And Holographic Projections?

1. What is the 3D technology for the naked eye?

Naked 3D is based on a grating principle that allows viewers to see 3D images without wearing 3D glasses, but it is essentially flat.

2. What is the holographic projection technique?

The holographic projection technique is based on the principle of interference and diffraction to reproduce the 3D images of real objects. Holographic projection can produce aerial phantoms, as well as real-life human-human interactions.

Field of Application

 Naked Eye 3D is used in shopping malls, bars, science and technology museums, corporate showrooms, real estate and virtual simulation.

3D holographic projection is widely used in product exhibitions, press conferences, stage shows and real estate.

Video source

 Naked Eye 3D, while also requiring a custom video source, can be converted from a regular 2D video source without re-enactment.

Holographic projection, where the video cannot be played with a normal video source, must be a special video.

Principle of imaging

 Holographic projection technology is based on the principle of interference and diffraction to reproduce the three-dimensional image of real objects. Holographic projection can produce air phantom, but also can realize the interaction of real people.

Naked eye 3D is based on the grating principle, so that the audience can see 3D images without wearing 3D glasses, but it is essentially flat.

Distance and Angle

 However, there are certain requirements on viewing angle and distance in order to achieve good 3D when experiencing 3D with the naked eye.

When a 3D hologram is projected, there is no restriction on distance and angle.
