.
Technology
Dolby 3D uses a Dolby Digital Cinema projector that can show both 2D and 3D films. For 3D presentations, additional filters are used in the projector. One filter each for the Left Eye and Right Eye. Each filter allows different frequencies of Red, Green, and Blue light to pass through each of them. The filters are able to each produce a common
RealD Cinema or linear polarization systems like Digital IMAX and are not considered disposable.[4] However, an important benefit of Dolby 3D in comparison with RealD is that Dolby 3D works with conventional projection screens.[5]
