1. What is Autostereoscopy?
Autostereoscopy utilizes the principle of lenticular lenses or parallax barriers to enable viewers to perceive 3D images without wearing 3D glasses. However, the actual display remains flat.
2. What is Holographic Projection Technology?
Holographic projection technology recreates three-dimensional images of objects through principles of interference and diffraction. Holographic projection can generate airborne holograms and enable interactions with real objects.
3. Differences Between Autostereoscopy and Holographic Projection
Applicable scenarios
Autostereoscopy: Applied in environments such as shopping malls, bars, science museums, corporate showrooms, real estate, and virtual simulations.
Holographic Projection: Widely used for product exhibitions, conferences, stage performances, and real estate presentations.
Video Sources
Autostereoscopy: Although specialized video sources are required, conversion from regular 2D sources is feasible without the need for extensive remastering.
Holographic Projection: Specialized video content is mandatory; standard video sources cannot be used.
Imaging Principles
Autostereoscopy: Utilizes lenticular or parallax barrier techniques to create the illusion of depth without glasses, but the display itself remains fundamentally two-dimensional.
Holographic Projection: Relies on interference and diffraction principles to reproduce three-dimensional images of real objects, capable of creating airborne holographic projections and supporting real-time interactions.
Viewing Distance and Angle
Autostereoscopy: Effective viewing requires specific distances and angles to achieve optimal 3D effects.
Holographic Projection: Offers freedom from distance and angle constraints, providing consistent viewing experiences from various positions.
In summary, autostereoscopy technology enhances viewer immersion without glasses but operates within a two-dimensional display framework. On the other hand, holographic projection technology utilizes advanced principles to create genuine three-dimensional images and interactive experiences.
