Can the DIRSIG software model a polarized system?

By Scott D. Brown - Posted on 08 September 2008

Yes, the DIRSIG model's internal radiometry engine automatically adjusts to propagate polarized fluxes when the need arises. If the sources of illumination (Sun, Moon, Sky, user-define sources, etc.) are polarized, or if the surface or volume optical properties are polarized then the model will shift to a full Stokes Vector and Mueller Matrix based calculus automatically.

The DIRSIG software can be used with MODTRAN4-P (an experimental, polarized version of MODTRAN4) and has several built-in polarized BRDF models.

The model can output fully spectral-polarimetric radiances for processing by external sensor models.
