LIDAR: Light Detection and Ranging

Description: A remote-sensing technique that uses a laser light source to probe the characteristics of a target

Recommended Product: Quantel Brilliant

Atmosphere control Density Temperature Wind Pollution... Distance,  speed measurement Rayleigh, Mie scattering Raman scattering Fluorescence Doppler shift

LIDAR: Principle

The laser light, back-scattered by particules, is collected by a telescope. The time delay between emission and reception represents the distance (time of flight). The intensity is an image of the particules density Laser/telescope unit is mounted on a mobile system

LIDAR: Typical set-up

LIDAR: Applications

Anhui Inst. Of technology, China

• Localisation of pollution emission
• Measure of the limit layer of the atmosphere
• Measure of the diffusion of pollution clouds
• Ozone hole

• Aerosol measurements
