Phase Electro-Modulation Holography Super high resolution film
Holography Electro-Holography Image data (input) Laser (backlight) M SLM (output) 3D image
Q : Source ?A : holography with SLM as the film.Q : Limitation ?A : 1. 2.Interference patterns record the Pixel sizes are too larger,“phase” information, but consume much than the wavelength,the resolution. so diffraction angles are almost 0°. M
Comparison Left & right sight Phase modulation Face tracking separation (Electro-holography) 1. Commercially available 1. Real 3D images 1. Real 3D images 2. Photo and Video 2. Full resolution 2. Photo and Video Adv available 3. No visual fatigue available 3. Low data volume in 3. No visual fatigue media files 1. Narrow view angle 1. Extremely big data 1. Very low resolution (naked-eye type) volume (photo only) 2. Narrow view angle 2. Bad user experience 2. Single viewer only due to the large pixel (glass-needed type) 3. High quality front size 3. Non-reasonable / fake camera and efficient 3. MonochromaticDisadv 3D images algorithm required images (transmission 4. Resolution reduction for face detection mode) (some types) 5. Visual fatigues (all types)
Conclusion• 3D images are the future.• The current 3D movies suck, which look fake and uncomfortable.• Electro-holography could be a promising 3D technique.• Full-color electro-hologram might be the next step.
