SUMMARY

This discussion focuses on calculating the reflected radiance from a single wave facet using Fresnel's equations. The user seeks to understand how to derive the radiance values based on the orientation of the wave facet. It is established that the statistical distribution of slopes contributes to the overall radiance, but specific calculations for individual facets require applying the principles outlined in Fresnel's equations. The conversation emphasizes the importance of angle dependency in determining reflected intensities.

PREREQUISITES
  • Understanding of Fresnel's equations for electromagnetic wave reflection
  • Knowledge of wave facet orientation and its impact on radiance
  • Familiarity with statistical distribution concepts related to slopes
  • Basic principles of radiometry and light reflection
NEXT STEPS
  • Research the application of Fresnel's equations in optical physics
  • Explore statistical methods for analyzing slope distributions in wave facets
  • Study the impact of angle of incidence on reflected radiance
  • Investigate advanced radiometric techniques for measuring surface reflectance
USEFUL FOR

This discussion is beneficial for optical physicists, remote sensing specialists, and anyone involved in analyzing surface reflectance in aquatic environments.

When I view the sea surface for a few seconds (using a camera), some wave facets have very high radiance values. I understand that there is a distribution of slopes and that one can determine a statistical radiance distribution, but how do I calculated the reflected radiance from a single wave facet with a certain orientation?

Google for "Fresnel's equations" which give the reflected and transmitted intensities of electromagnetic waves at a boundary, as a function of angle.
