    Abstract: Systems, methods and devices to detect target substances in confined or open spaces, and from the ground or remote locations are disclosed. A system includes a radiation emission source and one or more transducers configured to detect target substances. The transducer to detect target substances includes a filter that allows various wavelengths of light to pass through while attenuates or reflects others; and one or more chambers disposed within the optical path of the filter. The transducer may also include electromagnetic radiation detectors to detect electromagnetic radiation at wavelengths different from the wavelengths transmitted by the filter. The systems, methods, and devices disclosed allow shifting the detection range of phenomena in which the detection/observation technology is not efficient to other detection ranges where detection can be optimized.

    Abstract: A method of processing a remotely sensed multispectral or hyperspectral image captured in respect of an area of interest including a body of water so as to identify a submerged target, the method comprising obtaining (206), from hydrographic LiDAR measurements, data representative of water depth in respect of said body of water in said area of interest, performing (210) geo-rectification in respect of said hyperspectral image and said water depth data, applying a hydrologic radiative analysis process (211) to said multispectral or hyperspectral image so as to calculate, using said water depth data obtained from said hydrographic LiDAR measurements, data representative of (i) scattered solar radiation and (ii) spectral transmission between a surface of said body of water and a submerged target and subtracting (212) data representative of said scattered solar radiation from said multispectral or hyper spectral image and multiplying a resultant image by data representative of said spectral transmission so as to recover a spectral signature representative of said submerged target.

    Abstract: A method of detecting natural gas releases that includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of methane in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.

    Abstract: Apparatus for detecting an anomaly, (e.g. the presence of a hydrocarbon seep) at or near a water or land surface comprises means for generating a beam, preferably a pulsed beam, of primary light radiation, preferably ultra-violet light, and directing the beam towards the surface. The beam is sufficiently intense and of such a spectral composition that the beam causes the anomaly, if present, to emit secondary light radiation. The apparatus also comprises means for collecting the secondary light radiation, or means for collecting solar induced secondary light radiation, spectral analysis means for analysing the spectrum of the secondary radiation, and a high resolution, multi-element digitizing detector for recovering the analyzed secondary radiation. The detector has a plurality of detection channels positioned across the spectrum of the backscattered primary radiation and emitted secondary radiation, the channels being software configurable and under the control of a digitally addressable computer-operated controller. The concentration of used channels across the plurality of channels is adjustable and increasable in the regions of the spectrum of greatest interest and decreasable in the regions of least interest.
