Combined LOAS and LIDAR-system

摘要: A combined system of a LOAS and LIDAR comprises: arrangement optical elements for generating first coherent beam light at predetermined wavelength; second dichroic filter element directing the beams substantially on common path towards an aperture expander; least one output which directs both expanded from system, also receiving reflections to expander wherein are collected; separates collected corresponding back use in determining flow velocity, detecting object.
