    Abstract: Apparatus is disclosed for remotely measuring the diffuse attenuation coefficient K of ocean water from a platform such as an aircraft flying over the ocean. A pulsed laser beam is directed as a probe beam from the aircraft into the water to produce therein Brillouin backscattering signals which emanate back up through the water to the aircraft. An optical receiver in the aircraft receives and processes those backscattered signals. A very narrow optical bandpass filter passes the Brillouin signals to a photodetector, a digitizer and a data processor, the latter being programmed to compute the diffuse attenuation coefficient at predetermined depths and at the Brillouin wavelength. Measurements of the diffuse attenuation coefficient at various depths is accomplished by sampling and digitizing the Brillouin signals at predetermined intervals, each interval corresponding to a depth beneath the surface of the water. A preferred embodiment of the invention features similar apparatus having two signal-processing channels for simultaneously deriving the diffuse attenuation coefficient at two wavelengths by analyzing the upwelling Brillouin (blue) and Raman (green) backscatter generated by the probe beam. An alternate embodiment of the invention features apparatus for measuring the diffuse attenuation coefficient K of ocean water from a submerged submarine.

    Abstract: The present invention relates to a system for in-situ measurement of an apparent spectrum of a water body. The system comprises a floating device, and an optical sensing and conduction device, an electronic measurement device, a control circuit and a power supply device which are loaded on the floating device. The floating device comprises a floating body ring and an optical probe mounting frame which is provided on the floating body ring in a direction perpendicular to a ring surface. The optical probe mounting frame comprises a vertical mounting assembly and a horizontal connecting assembly. The horizontal connecting assembly is provided radially along the ring shape of the floating body ring, one end of the horizontal connecting assembly being connected to the vertical mounting assembly, and the other end thereof being connected to the floating body ring, such that the vertical mounting assembly is overhung outside the ring surface of the floating body ring, and meanwhile a vertical projection of the vertical mounting assembly is located in the center of the ring surface. A ratio of an inner diameter to an outer diameter of the floating body ring is 0.80 to 0.85. The floating body ring is provided with a water-tight cavity which provides flotage for the whole floating device and used for loading a necessary electronic device and a necessary power supply assembly. An optical probe is vertically mounted on the optical probe mounting frame. The device for in-situ observation of the apparent spectrum of the water body disclosed by the present invention may be used for directly measuring a water-leaving radiance Lw of the water body, and can furthest reduce the method defects, personal errors and device errors. The precision of a remote sensing reflectivity Rrs finally observed of the water body is improved remarkably, and the operations are simple.
