3D displays overview

 As in the case for stereoscopic 3D, 3D images can be seen by compounding the incoming images that are originally separated from each left and right eye in one’s brain. Currently, methods to see images without the aid of glasses are in the process of being developed, as is the Real 3D system.

The mechanism

Human eyes realise cubic effects as the right and left eyes capture two different images from two different angles. This is called “binocular parallax”, and is how most display products work to create 3D images.

Our eyes move unconsciously to image objects in our vision onto the retina (consisting of light-sensitive cells called rods and cones which absorb light).  This creates electrical impulses in the optical nerves that activate these light-senstive cells. Images created through this process from what the pupil senses are focused onto the upper part of the pupil.  In turn, the important information is then processed in the back of pupil in the visual system. Lastly, the brain combines all this information produced by the sensory organs (eyes) into perfect images, as the right half of the brain processes the left-eye visual field, and the casino francais en ligne left half processes the right-eye visual field.

Stereoscopic 3D Vision

The stereoscopic method can consist of the use of glasses as well as not using glasses; glassless-type 3D vision has been actively developed mobil casino thanks to the improvement of flat displays in the late ’90’s. The non-glasses type of vision does not apply glasses, but rather uses optical materials such as a Lenticular lens plate, film barrier, and LC shutter to form a flat display so that the images of the australians online casinos left and right eye can be seen separately.

Real 3D Vision

The Real 3D image method consists of a combination of Floating image 3D and Holographic 3D methods: by projecting lasers onto a rapidly spinning screen to create a three-dimensional image (Floating image 3D), and by recording the image information through the beams using the object and diffraction patterns formed by the reference points, and then projecting the reference beams onto the screen (Holographic method), the 3D image can actually be created.
