Abstract

An airborne laser IR thermographic system intended for remote gas detection is described. The system involves three channels of which one is active and two are passive. The active channel includes a 15 mW tunable laser diode illuminating the ground surface with 1 ms pulses of IR radiation at the wavelength of 1650 nm. The system sensitivity by the laser channel is about 100 ppm*m at 100 m (by methane). The two passive channels allow visualizing the ground surface in both the visual and mid-IR wavelength. The system has passed on-flight testing in cooperation with some Russian gas transportation companies.
