Abstract:
1. A method of visually detecting a gas leak of any one or more chemicals of a group of predetermined chemicals, the gas leak emanating from a component of a group of components in different locations, the method comprising: aiming a passive infrared camera system towards the component, wherein the passive infrared camera system comprises: filtering an infrared image associated with the area of the gas leak under normal operating and ambient conditions for the component with the at least one optical bandpass filter; receiving the filtered infrared image of the gas leak with the infrared sensor device; electronically processing the filtered infrared image received by the infrared sensor device to provide a visible image of the gas leak under variable ambient conditions of the area around the leak; and visually detecting the leak based on the visible image under the variable ambient conditions.
