RGBY Laser Projectors - v170120

Standard full colour analogue lasers use three primary colours: Red, Green and Blue. By mixing those together you can
pretty much get any secondary colour:
RGBY laser projectors use three primary colours (Red, Green, Blue) and additional yellow colour.
Of course the number and precision of the colours is determined by the modulation, stability and linearity of the system.
If the system is not stable enough, it will produce different colours every time it is used, making it virtually impossible to
match the colours of two systems at any one time. This is very often the case with systems from far east manufacturers
and with re-branded lasers that are being presented as European makes.

A scanning system is essentially two tiny mirrors, each moving on X or Y axis. By working together they can “scan” the
laser beam in all directions. Once a shape is scanned more than 20 times per second, it appears static to the human eye.
So any shape drawn by a laser is actually produced by one single laser beam being moved by these mirrors very quickly.
Every scanning system has a mechanical limit of how fast it can move its mirrors and therefore how many points it can
display at any one second and that is usually represented in Points Per Second at a certain scanning angle, i.e. 8 degrees.
