LLP Multitouch Zero Force Setup Take #2
Every since posting the results of my previous setup, I worked on improving some aspects of this setup.
During this time I decided to make a vertical version and at the same time test my new 850nm 10mW laser that this time featured more advanced version of the line generating lens. This reflected in fully uniform brightness across the line width and wider coverage angle.
Because of all of this, I found that using only one laser was sufficient enough for simple multitouch operation.
See it for yourself…
Here are the results:
