After testing my present setup for micro scanning, with a focusable red line (5mW) Laser, and merely dissatisfying results, I reach the decision to use a pico-beamer instead of the laser...I compared several beamers and think the MPro110 from 3M is the best solution, with a minimal picture diagonal of 120mm (@0,21m distance). Although the luminosity of the MPro120 (13lm) is almost twice as from the MPro110 (6lm), the minimal picture diagonal is just 200mm...
You added a lense to Your MPro110, what was the main reason for it? With a solution of 640x480 @ 120mm you still can get a laserthickness of 0,15mm. Or is it not sharp enough with that settings? What kind of lense have you used?
Thanks in advance..I hope I can submit some nice first scan results soon
