Hello laser enthusiasts!
I am new to the laser world, so forgive me for possible lack of understanding. I already spent several days looking for an answer in internet but had no success yet unfortunately.
I am working on a project where I need to display very simple shapes on a very wide area. Like dots, lines, circles, triangles. Those shapes should be bright and visible in normal illumination. And they should be displayed on surface from 1 meter distance, with angle around 110-120 degrees.
So I am trying to find out, can this be done with lasers and galvoscanners.
From what I found out, the scanning angles are usually quite small, given kpps stays hight - around 20 degrees. But then most galvos themselves can support 60 degree scanning.
I also thought to increase scanning angle by adding lenses. Like Pangolin's DiscoScan or something similar.
So my questions are as follows:
1. How much slower would be the kpps if you make scanner to scan on 60 degrees? If a need to draw only a few straight lines on this area, will it be enough for them to be displayed without significant flickering?
2. If I would to increase scanning angle with lenses, how much distortion will the beam have? I understand that if I draw a line from center to the side, it will be more thick on the side. But how much thicker? How can I calculate it?
Any additional comments are much appreciated!
