Abstract

An imaging radiometer is one of the most fundamental optics sensors for aircraft as well as satellite remote sensing. The important points on the future imaging radiometers are hyper-spectral resolution, wavelength running capability, and polarimetry would give us further information. The basic problem is the requirement for two simultaneous photometric measurements of every point in the sensor field of view for the two orthogonal polarization components. Then we developed a tunable spectral and polarimetric radiometer: an AOTF imaging spectro-polarization components. Then we developed a tunable spectral and polarimetric radiometer: an AOTF imaging spectro-polarimeter which uses an acousto-optic tunable filter (AOTF) as spectroscopic as well as polarimetric element. The specific point of the device is that we can simultaneously obtain two diffracted beams and images perpendicularly polarized to each other. The instrument employs an reviewing the concept, configuration and performance of the instrument, applications of the instrument will be presented: the laboratory measurements of light scattering by rough surfaces, the aerosol measurements from the ground, and more.
