An infrared (IR) spectral radiometric device for probing gas main pipelines and detecting gas leaks is described. The engineering description and the operating principle of a universal IR spectroradiometer mounted in a helicopter are presented. IR scanning of pipelines was performed in the wavelength range 8-12 μm by a helicopter flying along the routes of pipelines. The technique for measuring IR fluxes from extended heat sources is also presented. © 2010 Pleiades Publishing, Ltd.
