This is, perhaps, as one might expect, but it was worth trying anyways. Diffuse (non-relfective) objects work great... but the shinyness of the diamond plate is a real pain in our application.
We are going to try some sonar rangefinders, and do have a few applications in mind for the IR, but make sure you test your device on aluminum diamond plate at the earliest opportunity.
Good luck,

I suggest trying to find some VEX ultrasonics. They are cheap, already in a durable package and prewired (just need a female to female PWM cable, or the standard Y-splitters work too).
