Laser Cinema Projectors Posted on November 6, 2008 by Robin Previously lasers weren’t used for projection as they had a speckle effect. The Chinese Academy of Science has found that fusing three lasers (RGB) into a single white laser and then using traditional DLP technology to break the beam up into RGB again and the mirrors to put the picture onto the wall cancels this speckling. The resultant image can display around 80% of the human visible colour range compared to traditional wet film, which only catches 60% and is considered the ‘gold standard’ in these things. So. We have vibrant colours. But we also have a power consumption of only 35% of traditional xenon lamps in these projectors. Only the initial cost is very high. Robin
