Abstract: A device for detecting the presence of a hydrocarbon gas includes a an optical assembly and a digital analyzer. The optical assembly includes a laser source and an optical receiver, which may be an infrared optical receiver. The laser source is configured to output a beam towards a target, while the optical receiver is configured to receive a reflected portion of the beam reflected from the target. The optical receiver outputs a waveform to the digital analyzer, the waveform being based on the reflected portion of the beam reflected from the target that is receiver by the optical receiver. The digital analyzer is configured to receive the waveform from the optical receiver and determine if a hydrocarbon gas is present between the optical assembly and the target. The beam outputted by laser source of the optical assembly may be a collimated beam.

Abstract: A system for detecting a gas cloud has a camera having an image sensor, a display device and a processor. The processor is in communication with both the image sensor and the display device. The image sensor is configured to capture a plurality of images of a field of view. The processor being configured to receive the plurality of images from the camera, generate metadata from the plurality of images, evaluate the gas cloud based on the metadata and the internal component movements of the gas cloud if the gas cloud is being emitted from a single leakage point, and generate a color encoded image of the field of view. The color encoded image utilizing at least one color to display at least one attribute of the gas cloud and the single leakage point on the display device.
