Hi! I need to know if there is a way to measure distance without the use of infrared and ultrasonic? The range will be between 3cm to 5m with +-1cm of accuracy and it needs to be fast. I am building soccer robots which track a ball with infrared light. So I can't used Sharp IR sensors because of interference or ultrasound sensors as they are too slow. Something very similar to the Sharp IR would be awesome!
I was looking into laser range sensors but have not had any luck with finding any.
