Compact Handheld non-Laser Detector for Greenhouse Gasses

Abstract: 

Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include a non-laser light source and thermal imaging camera that allow for detection of a target gas (or gasses) that absorbs at least some of the light source's wavelengths of operation. The light source can be implemented, for example, with an incoherent infrared (IR) light source, such as a resonance lamp configured with a gas cell containing a volume of a gas that, when excited by electric discharge, emits a wavelength that is absorbed by the target gas.
