display 3of these stars beside each other within one single laser effect and that it would be
quite close to the scanner limit (3 × 10.500 = 31.500pps). This however applies than 8
degrees on both axes! If we start to increase the size of the projection (scanning angle) it is
necessary to either lower the number of points within the effect or drop down the scan-rate in
the control software (FPS) to a safe level – which may result in flicker.
From the example above we can also determine how many points this scanning system is able
to project if the scanning angle is not more than 8 degrees:
35.000 points / 35 Frames Per Second = 1.000 pps. This is the absolute maximum of how
many points we should be using when programming an effect if the scanning angle is not
more than 8 degrees.
In the following pictures you see the same star effect scanned at different scan rates at full
scanning angle (60 degrees).
Picture 1: the scan rate and/or number of points is too low. The corner points are more visible
than the lines between them and the whole effect flickers. The scan-rate and/or number of
points needs to be increased.
Picture 2: the scan-rate and/or number of points is about right. The whole effect has more or less
the same intensity and does not flicker.
Picture 3: further increasing of the scan-rate and/or number of points results in the effect
starting to distort, firstly around corners only. This indicates that you are exceeding the maximal
scan rate of the scanning system! If you operate the scanning system at scan-rates higher than
the maximum scan-rate of the scanning system the scanners will get damaged irreversibly due to
overheated coils damaging rotor magnets.
