Your eyes are great tools. Currently they’re reading these words on this screen (hi!), and they’re used to watch everything from paint drying to glorious movies. And while the movies are more fun to watch than paint drying, the latter of the two actually provides richer color.
The reason that movies aren’t giving your eyes the rich color that they so desperately crave is because of the range of color produced by current technology. The best digital theaters can only provide 50 percent of the range of color that your eyes can perceive (technical term: the gamut). While traditional film can give 60 percent, its decay makes it less desirable.
But, your eyes are on the verge of feasting on something fresh. New digital cinema projectors based on lasers offer the possibility of providing up to 80 percent of the gamut to your eyes. This is all thanks to a group of researchers at the Chinese Academy of Sciences in Beijing and a firm named Phoebus Vision OptoElectronics Technology.
While the concept of lasers being used as a projection source dates all the way back to the 1960’s, the bulk and expense of lasers made them impractical. Laser light of yesteryear also “speckled,” meaning that it would scatter off any rough surface, creating a shimmering and sparkling pattern. Or, in laymen’s terms, it would create a dull image.
Lasers still have a pretty sizeable cost; currently one of these projectors will cost 20 times as much as a normal digital projector. But, as the cost of lasers continues to drop, so will these prices.
