Laser Light Source
Three solid state lasers are used in the ARRILASER, producing monochro-
matic light beams in the colors red, green and blue. With a perfect Gaussian
shape, very long life expectancy and minimal size as well as power consump-
tion, they are the key to the ARRILASER’s unrivalled image quality.
The data for each color channel and pixel is fed to an Acousto-optical
Modulator (AOM) as a light intensity value, according to which the beam
intensity is controlled. The AOM translates the digital data of each pixel into
beam intensity in less than 17 nanoseconds.
Deflection System
Moving parts on the ARRILASER are designed to sustain a minimum of wear.
A new aerostatic bearing motor, which encounters no mechanical friction
during operation, is used to achieve the speed required for the deflection of
the beam. Line by line is written on film in an ultra precision linear stage.
A linear induction motor moves the stage through direct magnetic induction
without any additional moving parts such as gears.
