The Laser Falcon is a highly specialized device designed specifically to detect methane, ensuring that no false readings of other gases occur. This class 3R eye-safe laser employs Infrared Absorption Spectroscopy, emitting light in the spectral range of 1.65 μm.
Here's how it works: the laser emits light that reflects back and is captured by the sensor. The outgoing and incoming signals are then compared with the built-in reference cell. If methane is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter), providing precise measurements. These values are instantly transmitted to the remote control (RC) of the drone pilot and to UgCS software for further analysis.
