Stereo image is how it? Main is through 3D conversion Manager will entered of stereo 3D signal conversion into two a passive 3D output signal, then to separate of left, and right eye signal output to two Taiwan projector, through polarization 3D eyepiece watch, to are stereo image, due to signal is through 3D conversion Manager Active conversion, therefore this technology also is called active stereo imaging technology (difference Yu behind we will refers to of passive stereo imaging technology). In other words, if there is no case of Anaglyph glasses, we see in the images shown left and right eye respectively, which is the common phenomenon of ghost. To see the film, 3D glasses a lot.

Polarized glasses
　　Because watching a stereo left and right eye images when signals are separated, to avoid left eye signal out of sync (easy Imaging dislocation), need to be synchronized with the signal transmitter to synchronize left and right eye signals, in order to ensure that the human eye sees the image is about to coincide, which is solid. So why do I need a professional projection screens can show a clear stereo image? Because the image is seen in cinema through huge amounts of light on the projector to the screen is a member. But which some reflection light is effective of, that let we see image of, and some light is is harmful of (its equivalent to in strong too Sun Xia of leaves Shi produced of white reflection light, will interference we of eyes, let we see not Qing leaves, and produced Vertigo effect), and polarization characteristics metal screen is through joined special of material to elimination harmful of reflection light, to guarantee picture reflection to people eye of effective light not is interference.
　　Other words polarization properties of reflected light projection screen you can filter unwanted. Can be seen from the above described, associated equipment required for stereo imaging, and equipment requirements are very much on the environment. So there was no cinema in the professional environment, Office space, whether you can see 3D images, too? Today we present a 3D imaging technology.
