Abstract: Method for the quantification of the fugitive gas flow from a dispersed source (A) by monitoring with a remote detection optical instrument mounted on an aircraft (UAV) which moves at a determined height along a plane (S) perpendicular to the direction of the wind field (u), such wind field being known through suitable positioning of meteorological stations within and in areas neighboring the site to be monitored according to known techniques and use of commercially available diagnostic meteorological models. By this instrument discrete vertical measurements are carried out of the fugitive gas concentration averaged over said height along the whole width (W) of the plane (S) to yield corresponding mean vertical concentration values and, according to mean wind speed values detected at said discrete vertical measurements, a value of the fugitive gas flow (Q) is obtained by integrating the product of the mean vertical concentration values and of the corresponding mean wind speed values with respect to the surface of the sampling plane (S). The obtained value of the fugitive gas flow (Q) is corrected by a corrective factor (a) obtainable by comparing concentration values obtained by direct measurements and values calculated by dispersion models.

Abstract: A method of remotely measuring the diffuse attenuation coefficient K of ocean water from an airborne platform such as an aircraft. By directing a pulsed laser beam having a wavelength .lambda..sub.0 from the platform into the water, the beam interacts therewith to produce inelastic Brillouin backscatter signals at the wavelength .lambda..sub.1, where .lambda..sub.1 .noteq..lambda..sub.0. The desired backscatter propagate generally oppositely to the direction of propagation of the pulsed laser beam so that the backscatter can be received and collected at the platform. The upwelling optical energy includes the desired backscatter signals, which are separated out from the remainder of the upwelling optical energy. The separated backscatter signals are converted to equivalent electrical signals and periodically analyzed to generate therefrom the diffuse attenuation coefficient of the ocean water at the .lambda..sub.1 wavelength at periodic depths beneath the water surface. In another aspect of this invention both the Brillouin backscatter signals and the Raman backscatteer signals are separately filtered out to simultaneously measure the diffuse attenuation coefficient of the water at two distinct wavelengths. In another aspect of this invention the diffused attenation coefficient K is measured from a submerged platform, such as a submarine. This has the advantage of allowing deep ocean layers to be measured along with ocean water beneath the polar ice cap.

Abstract: A system and method for detecting an anomaly of an optically transparent or translucent object are disclosed. The system and method include a light source configured to emit light, a light transmission element having a textured surface, and an optical couplant configured to be disposed between the light transmission element and the object. At least a portion of the light emitted by the light source is configured to pass into the light transmission element through the textured surface and pass into the object through the optical couplant. At least a portion of the light that passes into the object internally reflects within the object and impinges on the anomaly to provide an illumination that indicates the location of the anomaly.

Abstract: The method of determining the presence of a spill of a petroleum product by the detection of a petroleum-derived volatile organic compound (VOC) generally has a step of providing an ultraviolet (UV) radiation generator and a receiver assembly aimed at a scene; a step of illuminating a distant target in the scene with a UV radiation beam, the UV radiation beam having an excitation wavelength being tuned to a resonance Raman excitation wavelength of the petroleum derived VOC; a step of receiving a return signal from the distant target; and a step of determining the presence of the petroleum-derived VOC upon detecting Raman scattering in the received return signal, the Raman scattering being indicative of a resonance Raman interaction between the UV radiation beam and molecules of the petroleum-derived VOC.

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.
