Advanced Laser Remote Sensing Probe for Gas Detection

Explore the world of laser remote sensing with our advanced probe, capable of detecting gas molecules through absorption, scatter, or fluorescence. The system includes an optical receiver, detection system, laser trigger, and more. Differentiate between molecules with Differential Absorption Lidar (DIAL) technology. Measure velocity, turbulence profiles, flow rates, and more with Doppler Lidar setup. Ideal for studying emissions, pollutants, and acoustic vibrations.
