Abstract
A system for open-path sensing of a property of a fluid in an environment comprises: a sensing light source; a pumping light source for outputting a pumping beam into the environment for inducing a change of light propagation characteristics of the fluid; wherein the system outputs a probing beam and a reference beam into the environment, such that the probing beam has a larger intersection with the pumping beam than the reference beam; wherein a first interferometer detects a phase shift and/or an intensity change of a received probing beam; and wherein a second interferometer detects a phase shift and/or an intensity change of a received reference beam.
