2 mirror system

This has been suggested by russellh.

Two mirrors will be used along with a tracking system. The tracking system would have a motor on a driven rotating base. A UV LED is used for the tracking system. Each mirror would rotate to face the other. Use a hard drive motor and drive circuit along with a balancing control system. Russelh is working on a prototype to demonstrate the concept.

Advantages

  • Auto-calibration (once set up)

Disadvantages

  • Complexity
  • Requires drive system
