Komt er Laser Cinema in de bioscoop ??

At ShoWest this week, Laser Light Engines (LLE) announced they have solved the speckle problem, opening the door for laser-based digital cinema.
Insight Media AnalystLasers have a lot of advantages for projectors in general and digital cinema in particular. The low étendue of a laser allows high-brightness out of small microdisplays. The lack of UV in laser light can be important too, especially for LC-based projection systems. Laser primary colors are very saturated, leading to very large color gamuts and lasers can also be energy efficient. They can certainly be more energy efficient than the xenon lamps typically used in digital cinema and in the long term they may be more efficient than UHP-type lamps or LEDs.
So why aren’t there more laser projectors out there? The fundamental reason is the cost of purchasing the lasers: they aren’t cheap. Secondary reasons are the effect of laser speckle on image quality and laser safety issues. (Bill Beck, Co-founder and EVP of Business Development at LLE) Beck said one of the techniques LLE has used for some time is increasing the angular divergence of the laser beam, thereby reducing its spatial coherence. Spectral broadening of the laser beam also decreases the coherence and speckle, as in the red and blue channels of the LLE system. The breakthrough at LLE, according to Beck, was broadening the spectral bandwidth of the green channel
the results in the LLE labs are satisfied with the result. Now, the only remaining barrier to laser cinema is the cost issue.
