Active remote sensing laboratory

The Active Remote Sensing laboratory includes five lidar systems (multi-wavelength Raman, eye-safe scanning mobile UV mini-lidar, ozone, fluorescence) and a sodar. These instruments provide profiles of aerosol, ozone and organic matter, optical parameters and wind speed and direction. Optical...

Fluorescence Lidar - FLUORES

Thumbnail

Our fluorescence Lidar (FLUORES) is designed to detect measure and map natural Dissolved Organic Matter (DOM), oil pollution and photosynthetic algae in water. It is optimized for operation from onboard a ship, stationary platform or from a moving vehicle. The dedicated software of FLUORES can...

Ozone Differential Absorption Lidar - OLI

Thumbnail

The principle of an Ozone Differential Absorption Lidar is based on differential absorption of optical radiation from atmospheric molecules. This technique is used to measure atmospheric gas concentration.

The laser emission / detection wavelengths are 266, 289, 299, 316 nm (having a total of...

UV depolarization eye-safe lidar - MILI

Thumbnail

The UV depolarization eye-safe Lidar system detects Mie/Rayleigh backscattering from atmospheric molecules and aerosol particles.

The laser emission wavelength is UV 355 nm (20mJ) and the detection channels are 355 cross and 355 parallel. The laser pulse duration is 3-6 ns (at 1064 nm),...

Multiwavelength Raman lidar - RALI

Thumbnail

The Multiwavelength Raman Lidar detects the Raman backscattering radiation from atmospheric water vapor, nitrogen, and Mie / Rayleigh backscattering radiation from atmospheric molecules and aerosol particles.

The laser emission wavelengths are 1064 nm (90mJ), 532 nm (50mJ) and 355 nm (60mJ) and...

IR-VIS aerosol lidar - LISA

Thumbnail

The IR-VIS aerosol lidar detects the Mie / Rayleigh backscattering radiation from atmospheric molecules and aerosol particles.

The laser emission wavelengths are 1064 nm (up to 100mJ) and 532 nm (up to 50mJ) and the detection channels are 1064 and 532 nm. The laser pulse duration is 10-12 ns...

SODAR

Thumbnail

The Sodar (sonic detection and ranging) system is used to remotely measure the vertical turbulence structure and the wind profile of the lower layer of the atmosphere.

The Sodar system operates by emitting an acoustic pulse and receiving back the signal. Both the intensity and the Doppler...

DOAS

Thumbnail

The Differential Optical Absorbtion Spectroscopy (DOAS) technique is based on the phenomena of selective absorption of electromagnetic waves from gases. At interaction between radiation and atmospheric components, the UV-VIS molecular absorption is the main process for DOAS technique.

The DOAS...
