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 digitising detector for recovering the analysed secondary radiation. The detector has a plurality of detection channels positioned across the spectrum of the basckscattered 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.

In one embodiment, a laser particle sensor (102) on or in a vehicle is provided. The laser particle sensor comprises an optical system (103); a processing system (116) coupled to the optical system; wherein the optical system is configured to transmit one or more laser light beams (112) to detect particles in a volume of freestream fluid (114), and to have the one or more light beams terminate on a portion of the vehicle on which the optical system is mounted; and wherein the optical system is configured to receive a backscattered portion of the one or more laser light beams transmitted by the optical system.
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:
Exemplary methods and systems for incorporating bio-sensors in drones to wirelessly detect biological molecules and hazards without exposing an operator to harmful contaminants or conditions. Bio-sensors can incorporate simultaneous dual-detection methods to ensure accuracy of measurements. Methods of operation include registering blank and safe air profiles for comparison against unknown air profiles to accurately determine the presence of bio-contaminants in unknown air.
Abstract:
Methods and systems for detecting oil proximate to a body of ice is disclosed herein. An example system includes an energy emitter disposed proximate to a first surface of a body of ice. An energy detector is disposed proximate to a second surface of the body of ice. The energy detector is used to map a distribution of oil proximate to the body of ice based, at least in part, on differences in energy transmitted through the body of ice.
