Personally I think Phil is quite right to call you a stupid troll. It's not 
as if you are not fishing for ideas.

I'm even less amazed that one of your skills appears to be hunting down 
information about someone who has the gall to call you stupid.....

Strange that.

Did you use Google to find out Phil is occasionally slightly obnoxious 
rather than reading this 'newsgroup' for a while?

Uuuuuhmmmmmmmmm............

Anyway.

Since I am brilliant, capable of thinking outside the box and it sounds like 
a 'fun' way of solving your problem. What you should really do is this....

Think in polar coordinates.

Pick one of the 'vertices' of your box as your 'origin'. Get yourself three 
'dual light pipe' type things and lay them out along the XYZ edges of your 
box as defined by that origin.

Plug the mechanical ends of your light pipes into some mechanical type 
rotating scheme, stepper motors with microstepping drive systems, so you can 
rotate them.

You will probably need some blu-tac to stop the water dribbling out.

Excellent opportunity for mechanical design of things that overcome dribble 
problems.

Then you shine a bit of light up one side of your dual light pipe thing and 
you recieve the reflected light back down the other side of it.

Lots of opportunity for transmission/modulation/detection/demodulation stuff 
there.

And rotate the pipes for maximum signal.

Lots of opportunity for feedback/control stuff there.

Once you have aligned all your pipes. Then all you have to do is do sums to 
convert the angles to where your object is.

Good stuff for the mathematics of the problem.

Now, kindly piss off and do your own research.
