The 7 Best Technologies Of The Colour Television

3D Visualization

Types of 3D displays
Stereoscopic
Main article: stereoscopy
Based on the principles of vision stereoscopic, described by Sir Charles Wheatstone in the 1830s, stereoscopic technology uses a separate device for each person see the stage for a different image on the left and right eye of the person. Examples of this technology include anaglyph images and tinted windows. stereoscopic technologies usually involve special glasses.
Autostereoscopic
Main article: Autostereoscopy
An evolutionary development of display technologies stereoscopic optical autostereoscopic adjust the screen, the user takes place, so that each eye sees the appropriate image. In general, allow the user to move headed by a certain amount without destroying the illusion of depth. shows include Automultiscopic pixels depends on view with different intensities and colors based on the angle vision, which means that a number of different perspectives of the same scene can be seen moving around the screen horizontally. In most of the screens change automultiscopic perspective is accompanied by the collapse of the illusion of depth, but some screens are available that can maintain the illusion that the light changes.
This category has the display technologies autostereograms.
computer generated holography
Main article: The team Holography creation
The hologram is a familiar fixture of the late 20th century, and research in holographic displays produced devices that are capable to create a light field is identical to that given by the original scene, the both horizontal and vertical parallax in a wide range of viewing angles. The effect is similar to look through a window in the scene is repeated, this may be the most convincing of the CGH 3D display technologies, but also large amounts of computation required to generate a detailed hologram largely prevent its application outside the laboratory. Some companies only produce holographic imaging equipment purposes commercial.
Volumetric cartel
Main article: Volumetric Display
In addition, there are screens in volume that uses a physical mechanism to show points of light in a volume. These displays use voxels instead of pixels. multiplanar volumetric displays include displays, with plans for multiple screens stacked and rotating screens, which explores a rotating panel of volume.
Other technologies have been developed for projects points of light in the air on a device. An infrared laser is focused on the target in space, generating a small bubble of plasma that emits visible light. In August 2008, the experiments do not allow speed 100 points per second. One of the issues that arise with this display system is the use of technologies that could be harmful to human eyes.
Problems
Each of these display technologies may be the limits considered, if the location of the viewer, and unsightly or bulky equipment great cost. Overcoming the latter is perhaps the major challenge for the imaging industry in three dimensions grass. The acquisition of 3D images without artifacts remains difficult. Photographers, cameramen and professional broadcast and film industry are not familiar with the complex configuration required to record images in 3D. There are currently no guidelines or standards for multi-camera parameters, placement and post-production treatment, as there 2D for conventional television.
