"Patented Remote Control Color Convergence Alignment Tool for RGB Laser Projectors"
MediaLas, Germany - By using a wireless remote control with joystick, or an automated external sensor, the three laser beams (red, green and blue) inside an RGB laser projector can be shifted and aligned at any time, even during a running laser show.
The exponental function of the remote allows shifting colors within a tenth of a milliradian to assure the finest and most exact matching. On fixed installations and/or cruise ships, this technology can be automated by using an external optical sensor somewhere in the installation room, which links wirelessly to the projector unit.
Two patents have been filed on this device.
