How a laser projector works

One of the questions we get all the time at X-Laser is “How do laser projectors actually work?” so we made a short video explaining how scanning and color mixing work together to create the shapes we all love.

We go through the layout and basic components common in most modern semiconductor laser light show projectors, then talk a bit about the specific signals used to control galvanometer scanners and laser diodes while showing you exactly how a circle is made.
