HI!

I am currently working on a VR project that requires a system of transmitters
and receivers.  I have a few questions that I hope will be easily answered:

1)	What is the most accurate and sfe waveform I can use.  In other
	words I need to measure distances within .001 of an inch from about
	20 feet.  It needs to be a fairly long wavelength, so as to not
	give me cancer!

2)	What kind of info does the reciever output (digital or analog?)

3)	How easy is it to triangulate with this setup?

I will have (8) transmitters and as many reicevers as I need.  What I was
thinking is to have each transmitter send a slightly different frequency
and the same receiver distinghush between them.  This would make things
a lot easier.  Thanks in advance!
