Abstract: Gas leakage monitoring systems and methods are provided, which use infrared camera(s) configured to capture images and to detect gas leakage at specified detection locations (SDLs) captured thereby, sniffer(s) configured to quantify the gas leakage at specified measurement points, and processing unit(s) in communication with the sniffer(s) and the camera(s), which are configured to associate and display sniffer point measurements within captured image(s) or video of the corresponding SDLs. The systems and methods generate a documentation of gas leakage measurements in association with images of the sniffers' positions during the measurements, e.g., measurement data being displayed on the image(s) of the sniffer(s) and provide additional combined analysis of images and measurements.

Abstract: System and method of quantifying a gas leak in a specified field of view are disclosed. The system may comprise a cooled detector and two interchangeable band-pass non-cooled filters. A first non-cooled band-pass filter transmits electromagnetic radiation in a first spectral band that coincides with a non-transparent leaking gas spectral band. A second non-cooled band-pass filter transmits only electromagnetic radiation in a second spectral band which coincides with a transparent leaking gas spectral band. The system may comprise a quantification unit arranged to process the images generated by the cooled detector to thereby determine, based on the images thereof, a flowrate of the leaking gas in the specified field of view. The system may comprise a detection unit arranged to determine, based on alternately generated multiple first spectral band images and multiple second spectral band images, a gas leak in the specified field of view.

Abstract: Imaging system and method for detecting the presence of a substance that has a detectable signature in a known spectral band. The system comprises a thermal imaging sensor and optics, and two interchangeable band-pass uncooled filters located between the optics and the detector. A first filter transmits electromagnetic radiation in a first spectral band that includes the known spectral band and blocks electromagnetic radiation for other spectral bands. A second filter transmits only electromagnetic radiation in a second spectral band in which the substance has no detectable signature. The system also includes a processor for processing the images to obtain a reconstructed fused image involving using one or more transforms aimed at obtaining similarity between one or more images acquired with the first filter and one or more images acquired with the second filter before reconstructing the fused image.

Abstract: An infra-red imaging camera comprises focusing optics for gathering infra-red energy from an external scene, and an uncooled and unshielded detector arranged to detect infra red energy. Internal temperature sensing together with approximation of the temperature response of the camera provides a time varying calibration that allows the infra-red energy received at the detector to be used as a temperature measurement for objects in the camera's field of view.

Abstract: An infrared sensor contains a sensor array and a sensitivity adjuster. The sensor array collects IR energy from an external scene, and the sensitivity adjuster adjusts a pixel grouping for light collection and/or readout, so that the resulting IR image is available at a required sensitivity level.
