PCAOM
At the other end of the scale is the Poly Chromatic Acousto Optic Modulator (PCAOM), a solid state, in-line device that allows for continuous brightness control of multiple laser lines to generate 16.7 million or more colours at MHz speeds. The PCAOM acts as a bulk diffraction grating which gives brightness control over the individual laser lines. Just as a TV set combines variable brightness of Red, Green and Blue to make the different colours you see on the screen, the PCAOM allows for variable brightness control of a number of laser lines (colours) that are added to create the desired output colours for projection. For example, one can combine 100% of the red line(s) with 50% of the green line(s) to produce an orange beam.
A PCAOM consists of a driver card or electronics package that takes the colour control signals and converts then to an RF signal that is fed to the cell. The cell is a crystal with a transducer bonded to it, that is inserted at the correct angle into the laser beam. The PCAOM has the advantages that it can produce 16.7 million (or more) colours, has very high response speed as it is a solid state device thus allowing for multiple colours and blanking within a single frame.
natuurlijk kan het ook zo maar das natuurlijk niet snel genoeg
en als we dan toch bezig zijn hier nog wat leuke dingenn
