Ever heard of Rube Goldberg?
Rather than using three separate sensors looking at the same thing with varying gains, you could definately put a little TOO much effort into this thought.
Take a small motor. Very small. Mount a flat-head screw diver bit to it. Program it to constantly, or in some sort of pattern, adjust the gain on a single sensor, preferably with the robot stationary. That should theoretically give you the strength of the reflection, wouldn't it? Would be a LOT of fun to engineer and program, don't you think? Although, the sort of pattern used by the screw driver bit might be useful for a whole robot that lost its way. Just a late evening thought.
