    Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include an unstablized laser and thermal imaging camera that allow for detection of gas that absorbs at least some of the wavelength of operation of the unstablized laser. The devices can be operated at a low-power density for safety and/or may be configured to mitigate wavelength hopping associated with unstablized laser light sources.

    Abstract: Systems and methods for fast and sensitive standoff surface-hazard detection with high data throughput, high spatial resolution and high degree of pointing flexibility. The system comprises a first hand-held unit that directs an excitation beam onto a surface that is located a distance away from the first unit and an optical subsystem that captures scattered radiation from the surface as a result of the beam of light. The first unit is connected via a link that includes a bundle of optical fibers, to a second unit, called the processing unit. The processing unit comprises a fiber-coupled spectrograph to convert scattered radiation to spectral data, and a processor that analyzes the collected spectral data to detect and/or identify a hazardous substance. The second unit may be contained within a body-wearable housing or apparatus so that the first unit and second unit together form a man-portable detection assembly. In one embodiment, the system can continuously and without interruptions scan a surface from a 1-meter standoff while generating Raman spectral-frames at rates of 25 Hz.

    Abstract: A spectroscopic chemical compound identification system includes a container, a memory, a spectrometer, and a processor. The container receives unknown chemical compound. The memory stores a plurality of spectral signatures corresponding to known chemical compounds. The spectrometer measures a spectral signature of the unknown chemical compound through the container. The processor is connected to the memory and the spectrometer, performs a comparison of the spectral signature with at least one of the plurality of spectral signatures, and determines the identity of the unknown chemical compound from the comparison. The system can be housed in a portable handheld housing. A chemical compound can include a pharmaceutical or controlled substance. The system can be also be used to determine if a pharmaceutical or controlled substance is present within an unknown mixture of chemical compounds.

    Abstract: A gas detector (10) that is arranged to sense the concentration levels of target gases oxygen, methane, carbon monox-ide, and hydrogen sulphide, within a gas sample from an environment surrounding the detector. The gas detector (10) comprises laser sources (12a-12d) that are arranged to transmit radiation through the gas sample at four target wavelengths that correspond approximately to the optimum absorption wavelengths of each of the target gases and an optical detector (16) that is arranged to sense the intensity of the radiation transmitted through the gas sample at each of the target wavelengths. A control system (22) generates representative concentration level information for the target gases based on the level of absorption of the radiation transmitted.

    Abstract: The invention concerns a portable device for reading a fluorescent-labelled, membrane based assay, to detect the presence of an analyte in a sample. The portable device comprises a light sealed housing which includes a receiving member to receive a membrane based assay. The light sealed housing comprises a first light source for illuminating a first portion of the membrane with light, a first photodetector, a light guide and a microprocessor. The first photodetector is operable to detect fluoresced light emitted by an excited fluorescent label captured by a reagent laid down in the first portion of the membrane and to measure an intensity of the fluoresced light. The light guide guides illuminated light from the first light source to the first portion of the membrane and guides fluoresced light emitted by the excited fluorescent label to the first photodetector. The microprocessor is operable to process the measured intensity of the fluoresced light to determine whether the analyte is present.
