1. In this way, physical optics recovers Brewster's angle. 2. It covers little of what would now be termed physical optics . 3. Gaussian beam propagation thus bridges the gap between geometric and physical optics . 4. It represents a simplified version of the more rigorous treatment of physical optics . 5. It was invented by a U . S . company called Physical Optics Corporation. 6. Scattering off of matter is radiative transfer, and the Wolf effect is physical optics . 7. Gibbs also worked on the application of Maxwell's equations to problems in physical optics . 8. Award honors a scientist who has made outstanding contributions to the scientific field of physical optics . 9. It is also used for simulation and analysis of optical systems using both geometrical and physical optics . 10. This work led to a theory of diffraction for light and opened an entire area of study in physical optics .
