I'd be curious to see images or video from the actual event.

We used polarizers 2 years ago, and testing with them showed polarization was preserved upon reflection (done by rotating the illuminators polarizer 90deg out of phase with the cameras). In practice though you would want to use a single polarizer covering both camera and light.

Our first competition is March 8th, hopefully we'll have some videos from that event. One challenge at this time is the infrared camera itself is a bit useless for the drivers, so we may end up dynamically adjusting the game as the match progresses.
