If you want, you can add a sine wave to the y-axis at the same time as a sine wave on the x-axis, but it has a 90-degree offset.

Then you will see that the bottom mirror of the galvanometers rotates on its axis to move the beam from the left side to the right side and back again.

When you have a sine wave on your x-axis, you need to move your points slowly from negative 5 volts to positive 5 volts.

But, what happens if you sweep voltage through a range of values instead of jumping from negative 10 volts to positive 10 volts? In this case, you can use a sine wave to move through all the points smoothly. Now you understand what signals the Galvos are looking for, and you can feed them information a bit faster. Now, if you want to change this to positive 10 volts X and positive 10 volts Y, the Galvos will move this point to the top right of your scan field.

When you want to send the projector a negative 10 volts X signal and negative 10 volts Y, this will put your point at the bottom left.

At zero volts, the y-axis mirror is centered, and at negative 10 volts, the mirror is at its powerful point to the bottom, and a positive 10 volts, the mirrors are at its extreme point to the top. And at positive 10 volts, the mirror is at its most powerful point to the right.Īt zero volts y-axis, the mirror is centred, and at negative 10 volts, the mirror is at its extreme point to the right. The x-axis mirror is centred at zero volts, but at negative 10 volts, it is at an extreme point to the left.

The industry standard is to control this position with a plus and minus 10-volt signal.

The Galvos driver positions them very quickly and accurately based on a control input from the controller.Then it bounces off of the top mirror, which controls the y-axis of the output. It controls the x-axis movements of the output. The laser beam hits the lower mirror first.

The Galvos is a set of galvanometer motors and a block with high-efficiency mirrors mounted on the shafts. This single beam path goes into a set calledCalvos or a Galvos set.At the same time, the others reflect, thus allowing you to connect multiple laser diodes into a single beam path. At first, a particular set of dichroic glass mirrors combines the colours, and this unique mirror allows various laser light wavelengths to pass through.The laser light projector has a standard configuration of red, green and blue at the front part. Frequently those diodes are combined in a single internal housing that’s called a laser diode module. On the other hand, the front section is where the laser diodes are located.

But the major function is to interpret the signal from your lightning console or computer and send it into something the laser diodes and scanner can use to create patterns. This part can control things like temperature, monitor the power system and so on. The back section of the laser light projector comes with all its control circuitry. Front and back parts of laser light projectors Before this, let’s discuss what an ordinary laser light projector has. To get a crystal clear view of how it works, we will demonstrate its working procedure. The galvanometers move the single beam through space quickly enough to look like a solid line to the human eye. Those mirrors are mounted on tiny high-speed precision motors called galvanometers. These systems work by taking one or more laser beams, combining them, then routing that single beam into a set of mirrors. When people think of outdoor Christmas laser light shows, they think of a scanning laser system producing beams in the air or images on the wall. The indoor and outdoor laser light projector works straightforwardly.

So, today we are going to describe how a laser projector works.
