Timing

Olympic luge is timed to the thousandth of a second for comparison, the blink of an eye takes 12 thousandths of a second.Luge is timed using photoelectric sensors at the start and finish. The setup has a light transmitter receiver pair at each end of the run. The transmitter is on one side of the track, and the receiver is on the other. At the start, the slider triggers the timer when he crosses the line because he blocks the light beam. At the finish line, he stops the timer the same way.
