Abstract: A method of optimizing detection of known light sources is provided herein. The method may include: positioning a plurality of cameras having different spectral bands to have at least partially identical fields of view in respect to a view that contains the light sources; capturing images of the light sources by the cameras at different spectral bands; estimating, for each pixel and all cameras, relative fraction values of collected sun light and of collected light sources; deriving, for each pixel, optimal fraction values of sun light and of the light sources, by minimizing, for each pixel, a mean square error estimation of an overall radiation with respect to the estimated relative fraction values.

Abstract: An infrared optical system having a spectral range for achieving a fog penetration distance of at least 2.75 Runway Visibility Range (RVR) is provided herein. The optical system may include a single set of optical elements designed to have a wavelength range extending beyond 1.2 μm toward shorter wavelengths and comprising a short-wavelength infrared (SWIR) range and at least one of: a middle-wavelength infrared (MWIR) range and a long-wavelength infrared (LWIR) range, to enhance a detection range of the infrared optical system, wherein the single set of optical elements is laid such that the both the SWIR range and the at least one of the MWIR range and the LWIR range of infrared radiation pass through all of the optical elements.

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.
