MR-FAT UAV Fourier transform infrared telemetry imager is a scanning gas infrared remote sensing telemetry instrument based on passive Fourier transform infrared spectroscopy technology, which can automatically detect and alarm target gas clouds, and can identify gases. Types and semi-quantitative gas concentrations. And mounting this instrument on a drone will make it more maneuverable.

Infrared spectrum is also called molecular fingerprint, and the infrared spectrum characteristics of different gas molecules are different. Most toxic and harmful gases have characteristic peaks in the long-wave infrared band. Fourier transform infrared spectroscopy technology uses the infrared spectral characteristics of gases for detection and analysis.
