- A group at the mechanical engineering department at Georgia tech made
- an optical correlator for usage in mobile robotics. I believe it is
- reported in the SPIE conference Mobile Robots III.

- Incidently, it was never actually sold-Industry wasn't interested at
- the time. It was developed as an alternative to odometry.
- Supposedly it was potentially quite accurate.
