Wave propagation and imaging through fog and cloud

Back to Research Main

 

Summary

Imaging and detection of objects at optical wavelengths offers better resolution than at microwave or millimeter wavelengths. However, the imaging is severely affected by scattering from fog and clouds. This project investigates optical wave propagation and imaging through clouds by using the vector radiative transfer theory. The point-spread function including complete polarization characteristics is studied with numerical examples at 1 m wavelength showing the effects of aperture size and optical depth on the shower curtain effects.
