Abstract
At least one second beam of light from a first beam of light generated by a laser is directed into an atmosphere. Light therefrom scattered by molecules or aerosols in the atmosphere is collected by at least one telescope as at least one light signal, which together with a reference beam from the first beam of light are simultaneously processed by an interferometer, and resulting fringe patterns are imaged onto a detector adapted to output a resulting at least one signal responsive thereto. In various aspects: a plurality of transversely separated light collectors collected the scattered light; at least two telescopes are associated with a common second beam of light; or the telescope is coupled to a gimble mount that provides for positioning a region of overlap of the second beam of light with the field of view of the telescope.
