Mechanically scanned laser display
This project is on hold, probably for a very long time... I stopped doing "fun" projects that don't really serve a purpose. The focus is on "functional" projects lately. This page is maintained as an archive, to maybe spark an idea for someone else.
The idea for this project is to have an array of 16 laser beams pointed towards a two-sided mirror strip (salvaged from a handheld scanner head), rotating along its long axis. This way, the 16 laser beams are being scanned along a surface twice per mirror rotation The mirror is slightly slanted, interleaving or alternating the laser beams to produce 32 or even more scan lines. A microcontroller controls the 16 lasers and the mirror, making it possible to produce images and text. Something like this, actually. The hard part will be to make this display compatible to a widely used graphic display, in order use ready-made software to display all sorts of cool stuff. Another hurdle to be taken is the optical distortion because the radially scanned image is being projected onto a flat surface.
At this moment, all I have is the main parts. Here are the 16 lasers:
And 2 slim rectangular front-reflecting (important!) mirrors, salvaged from hand scanners:
...and that's all for now... ...to be continued... ...someday...
