    Abstract: A method and system is disclosed for determining the integrity of a closed container. The method and system includes the steps of positioning the container in a surrounding, changing a gas pressure, a gas composition, a gas concentration, or any combination of gas pressure, gas concentration and gas composition, in the surrounding. Thereafter subjecting the container to an optical sensor, non-intrusively, the sensor being sensitive to at least one gas, and the sensor is configured for detecting the at least one gas inside the container. Reading a signal from the optical sensor related to a gas pressure, a gas concentration, a gas composition, or any combination of gas pressure, gas concentration, and gas composition, inside the container. The behaviour of the signal being indicative of breach in integrity of the container.

    Abstract: The disclosure relates to system and method for determining at least one property of a porous medium and includes performing a first measurement on a sample of the porous medium obtaining an optical path length through pores of the porous medium using a first sensor applied utilizing a first optical technology, e.g., TDLAS or GASMAS; performing a second measurement on the sample of the porous medium obtaining a total optical path length through the porous medium using a second sensor utilizing a second optical technology different from the first optical technology, e.g., time-of-flight; and calculating an optical porosity of the porous medium based on the optical path length through the pores, the total optical path length through the porous medium, and a predetermined refractive index of the bulk medium.

    Abstract: A compact apparatus for detecting multiple gases, e. g., in a closed container, is disclosed. The apparatus comprises a multi-wavelength laser module (4) and a multi-wavelength detector (1), the detector comprising a stack of at least two material layers (2, 3) arranged along the same optical axis, wherein each layer is designed to detect a specific wavelength range different from the wavelength ranges detected by the other layers. The laser module may comprise at least two laser sources (5, 6) configured to emit different wavelengths, said laser sources being positioned close to each other so as to enable overlapping laser beam paths (7). The laser sources may be tunable diode laser or may be made of different laser chips arranged in a same laser housing. The apparatus may be configured as a TDLAS apparatus.

    Abstract: An system and method is disclosed for determining a concentration of at least one gas in a container. The system and method includes detecting light reflected by a surface inside or behind the container, or light refracted or scattered by the container, with a detector, wherein the detector provides a first signal related to an intensity of the reflected light, and a second signal related to a position of reflected light being detected. The first and second signals are used for estimating a concentration of the at least one gas inside the container.
