WebAvijit Lahiri, in Basic Optics, 2016. Abstract. Ray optics, or geometrical optics, is based on the short-wavelength approximation of electromagnetic theory.It is defined in terms of a package of rules (the rules of geometrical optics) that can be arrived at from the Maxwell equations in a consistent approximation scheme, referred to as the eikonal … WebBrian W Pogue PhD – Laboratory PI. Brian founded the MOXI research group when he came to serve as Chair of the Department of Medical Physics in 2024. His research program focuses on development of unique optical tools and techniques for advanced surgery and radiation therapy guidance, photodynamic therapy, molecular imaging, and theranostics.
