Dolby Cinema: Twin laser projectors + object-based 3D audio = awesome

Ars Technica: A representative from Dolby Labs explained the Dolby Atmos and Dolby Vision features that together make up Dolby Cinema. Like IMAX-with-laser, Dolby Vision uses lasers as light sources instead of the usual high-intensity discharge bulb. This allows the projection to be much brighter, and the contrast level to be much higher, than with normal DLP.
