Our Technology
What is 3D:
NVision's Visualisation equipment use 'Active 3D' when viewing an image on the screens. The following section will explain how this technology works and how it differs from 'Passive 3D' which is commonly used in cinemas.
Active 3D:
Active shutter glasses (sometimes referred to as Liquid crystal shutter glasses) are glasses used in conjunction with a display screen to create the illusion of a three dimensional image. Each eye-lens contains a liquid crystal layer which has the property of becoming dark when a voltage is applied to it. The glasses are controlled by an infrared, Bluetooth, or other kind of transmitter that sends a timing signal which allows the glasses to alternately darken over one eye and then the other in synchronization with the screens refresh rate. Meanwhile, the display shows alternate images for the perspective of each eye, using a technique called alternate-frame sequencing, which achieves the desired effect of each eye seeing only the image intended for it.
LCD shutter glasses are mostly able to eliminate "ghosting" which is a problem with other 3D display technologies such as polarized glasses. Moreover, unlike red/cyan colour filter 3D glasses, active shutter glasses are colour neutral enabling 3D viewing in the full colour spectrum.
Passive 3D:
Polarized 3D glasses create the illusion of three-dimensional images by restricting the light that reaches each eye, an example of stereoscopy which exploits the polarization of light.
To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through different polarizing filters. The viewer wears low-cost eyeglasses which also contain a pair of different polarizing filters. As each filter passes only that light which is similarly polarized and blocks the light polarized in the opposite direction, each eye sees a different image. This is used to produce a three-dimensional effect by projecting the same scene into both eyes, but depicted from slightly different perspectives. Several people can view the stereoscopic images at the same time.
Anaglyph 3D:
Anaglyph images are used to provide a stereoscopic 3D effect, when viewed with glasses with two lenses of differing colours, for example red and cyan. Images are made up of two colour layers, superimposed but offset with respect to each other to produce a depth effect. Usually the main subject is in the centre, while the foreground and background are shifted laterally in opposite directions. The picture contains two differently filtered coloured images, one for each eye. When viewed through the colour coded anaglyph glasses, they reveal an integrated stereoscopic image.
