Images from my PicoPro tear-down

I'll add more photos to this post as I have time to take them and label the components. Feel free to re-use these pictures but please provide a link back to this blog for attribution when doing so.

Laser light path within the optical engine of the Sony/Microvision  module

Ruler displayed for scale

Better view of the lasers GRBGR, left to right. In front of each laser is a black plastic case that contains a very small beam expanding lens. I think the lenses are actually plastic. The five square cut-outs you can see in front of each black plastic case are for sensors that provide optical feedback to the circuit board and they turn off the lasers if any of the beams are interrupted.

Here are a few views of the MEMS unit next to a dime (click to enlarge). Unfortunately there's no readily obvious manufacturer's mark on it, though there is a small QR code. The writing on the ribbon connector says: "PB0133286-002 MICROVISION, INC."

The top and bottom of the projection module PCB, labeled as best I can. The bottom image is reversed right to left so that it lines up with the top image. Click for a larger version.
