How Does .d Technology Works? - .D Technology Information

To see how 3D technology works; we must first see how human sight works. Humans possess two eyes approximately 3 inches apart. This distance creates two slightly different images. These images are transmitted to the head and so the mind will make a place in where space and depth can be perceived.

For 3D technology to make this same character of place in your brain, it inevitably to john your mind into seeing two separate images from the same source.

How 3D technology does this, is that it places two slightly different images over each other or in alternating sequence. The soul must then break a set of 3D glasses that will dissect this picture and send it to the right eye.

There are presently two types of 3D glasses technologies, active and passive. Active glasses have electronics that will convert the display. Passive glasses have no electronics and use a different way to analyze the images.

Two of the currently used active 3D glasses technologies are liquid crystal shutter glasses and display glasses. Liquid crystal shutter glasses contain a liquid crystal that can stop or pass light through in synchrony with the images on the display. It uses the conception of alternate frame sequencing which places the different frames in alternating order instead of over each other. Display glasses are head mounted stereoscopic displays. Each eye has its own display and they are somewhat different so the other.

Two of the currently used passive 3D glasses technologies are linearly polarized glasses and circularly polarized glasses. Linearly polarized glasses uses two images that are superimposed over each other and the glasses uses an orthogonal polarizing filter to analyze the image. This technology requires the spectator to retain the brain level because tilting of the head will cause the images to run over each other. Circularly polarized glasses use a span of circular polarizers placed opposite each other. With this technology the spectator can angle their heads left and right without the images bleeding into each other.
