You might want to do some basic sums before you start. Light goes at
approximately 300 million metres/second. To measure to an accuracy
of a meter would thus require an accuracy of clock the inverse of
this (3ns or so). On any micro this is a major challange....

I'd suggest you use a different technique!

I'd use a CPLD or FPGA to do the timing. The commercial systems probably do 
it that way.
