We normally classify laser lights into 2 big groups:

1. laser lights built in step motor
These laser lights can only display beam show with patterns.

2. laser light built in scanner/galvo
These laser lights can display animations, beam show. If laser lights are with ILDA function, we can create our own animations via laser software linked to PC.
The higher scanner speed, the more complicated animations can be displayed.
Scanner speed is counted by kpps (k=1000, p=points, p=per, s=second).
Scan angle is counted by degrees. The higher degrees, the more coverage on the space by laser beams.
