Blanking

What is Blanking?

Blanking is the capability of a show laser system to rapidly turn on / off the laser when displaying visible lines, graphics and animations. E.g. when drawing a text, the laser system needs the ability of blanking to omit the empty spots between the characters. Otherwise it would always look like cursive.

What are blanking errors?

Especially cheap laser devices are not capable of proper blanking. Every time the show laser has to skip a line between charakters or patterns, a thin line remains and can be seen on the projection surface.

How can I improve the blanking of my laser system?

Blanking errors occur because of bad cooperation between laser sources and the scanning system. This can be improved by better electronics and drivers or with a professional show laser software.
