Technique for the Measurement of the Transit Time of an Optical Signal

Abstract

DURING the past several decades numerous arrangements have been developed for measuring the time of transit of a beam of light propagated over a tropospheric path. In these arrangements the transit time is determined by measuring the phase shift of modulation on the beam1–6. Most of this work has been carried out in connexion with measurements of (1) the velocity of electromagnetic waves, (2) geodetic distances, and (3) atmospheric turbulence.
