活动简介

The use of sensors for active and passive remote sensing of the Earth and its atmosphere, for free-space laser communication, and for high-resolution imaging of ground-based and airborne objects are fields of growing interest for both civilian and military applications.

Such high-resolution space-to-ground (or ground-to-space) optical sensing systems use spectral regions varying from UV to Radar. However, they all must deal with long path atmospheric geometries and different radiating backgrounds. Instrument and measurement analysis therefore depends crucially on a thorough understanding of all optical effects that limit the sensor performance through an atmosphere that acts as an absorbing, scattering, and radiating random medium. Increasingly important in this area are modern methods used to ameliorate these effects through compensative hardware, algorithms, and measurements of atmospheric parameters at different locations.
