Methane is invisible – but it leaves a spectral fingerprint. By integrating the HySpex SWIR hyperspectral camera into the AISPECO LITE airborne pod, operators can detect, localize, and quantify methane and hydrocarbon emissions from safe stand-off distances using reflected solar radiation in the shortwave infrared spectrum.
Methane (CH₄) strongly absorbs solar radiation at specific wavelengths in the Short-Wave Infrared (SWIR) region, particularly near:
The HySpex SWIR sensor captures hundreds of narrow spectral bands, allowing detection of subtle absorption features caused by methane plumes.
