Hi Pulse -> (fast) LED LED -> splitter splitter -> 2 (fast) photo diodes
Start with the diodes in the same plane, calibrate out the systematic delays. Likely with a deliberate offset (coax cable length). Move one detector and note the change in time. Distance would be highly dependent on how fast your LED is and how fast your detectors are.
