Atmospheric Remote Sensing with Rayleigh/Mie Lidar

One aspect of Ophir Corporation’s laser radar (lidar) expertise is the use of Rayleigh and Mie light scattering returns. Rayleigh/Mie lidar relies on light interaction with the constituents of the atmosphere — scattering from both atmospheric aerosols (Mie scattering) and atmospheric gas molecules (Rayleigh scattering).

Ideal Applications for Rayleigh/Mie Lidar

Rayleigh/Mie lidar is ideal for innovative avionics and ground-based sensors; particularly for measuring air data in clear air environments found at aircraft operational altitudes. Few aerosols are present at aircraft operational altitudes, so our ability to collect light returns from scatter off of the air molecules present (Rayleigh scattering) is critical to making atmospheric measurements.

Temperature and pressure measurements for ground-based and airborne applications also benefit from the ability to measure light scattering off of molecules. Rayleigh/Mie lidar utilizes both types of scattering phenomena (from air molecules and aerosols) and enables these returns to be analyzed separately to determine temperature and pressure of the atmosphere.
