    Abstract: A system for detecting volcanic plumes using a camera on an aircraft, a distant point-like source of light, and a computerized method of processing images acquired by the camera to detect phenomena indicative of the presence of volcanic plumes in a volume of space intersected by light from the light source. A computer system is programmed to determine whether the image data from the camera has characteristics indicating that the imaged light had passed through a volcanic plume or not. In response to detection of a volcanic plume in the flight path of an aircraft, the computer system outputs an alert activation signal to an alert device that produces a visible or audible alert.

    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: An apparatus for determining the fluorescence of materials in a scene which includes optical means to collect radiation from the scene. Means are provided to divide the collected radiation into first and second beam paths. The first beam path traverses a first filter centered on a Fraunhofer line and having a passband which extends into the solar continuum on either side of the Fraunhofer line. The second beam path traverses the first filter and a second filter, also centered on the Fraunhofer line, with a passband on the order of half the bandwidth, at half-depth, of the Fraunhofer line. Means are provided to image the first and second beams onto first and second detector arrays, respectively. The image on the first detector array is registered with the image on the second detector array. Co-adding means are provided whereby successive detector pixels at successive time intervals corresponding to a single point on the ground are added and averaged. The time interval is a function of a constant clock rate and a V/H signal. A single detector is provided to detect the intensity of direct solar radiation outside the Fraunhofer line. A processor compares the value of intensity from the co-added point on the ground from the first and second detector arrays and the single detector to determine fluorescence at each point on the ground in the scene being viewed. In another form, where an optical laser illuminator is employed, the first beam path traverses a first filter which only allows the laser radiation to pass. The second beam path has a passband which passes the emission spectrum of a material excited by the laser radiation.
