Optical design and optimization with physical optics
SPIE Proceedings, 1990This paper describes implementation of optimization methods in physical optics modeling, similar to those used in geometrical lens design, but capable of treating the greater range of performance aspects which may be considered in a physical optics treatment.

We outline the basic principles of optical tweezers as well as the fundamental theory underlying optical tweezers. The optical forces responsible for trapping result from the transfer of momentum from the trapping beam to the particle and are explained in terms of the momenta of incoming and reflected or refracted rays.

Physiological Optics and Physical Geometry
Science in Context, 2001ArgumentHermann von Helmholtz’s distinction between “pure intuitive” and “physical” geometry must be counted as the most influential of his many contributions to the philosophy of science. In a series of papers from the 1860s and 70s, Helmholtz argued against Kant’s claim that our knowledge of Euclidean geometry was an a priori condition for empirical ...
