We show that the authors used the geometrical optics approximation model for gravitational lensing and thus they gave an overestimated rate of possible events for possible sources of gravitational radiation for the advanced LIGO detector.
In this paper, a first order, geometrical optics focus model for a camera looking through multiple planar interfaces was presented.
The nascent discipline of direct measurement of phase functions of ice crystals in conjunction with particle imaging and forward modelling through geometrical optics derivative- and Transition matrix-codes for the first time allow us to obtain a deeper understanding of the optical properties of real tropospheric ice crystals.
A detailed model of the optical efficiency for the solar collector with inner CPC is built, analyzes the parameters of the model, such as geometrical optics efficiency, transmittance, reflectance and absorption ratio, with methods of ray tracing and geometrical optics.
Differently from analytical models that use only the geometrical optics approach with no correction for the stress-optical effects, here the refractive index is corrected at every bending angle to consider the stress-optical effects observed polymer optical fibers.
With geometrical optics it is difficult to accurately explain and model such phenomena as interference and diffraction, or to predict the exact amount of light reflected from a material interface.
Feyerabend subsequently added the example of geometrical optics and wave optics (1965b, 227).
Geometrical optics: ray matrices, Gaussian beams, optical instruments, and radiometry.
Courses include modules looking at optical principles, ocular anatomy, geometrical optics and how ophthalmic lenses (better know as corrective lenses) repair refractive errors and vision disorders.
Known collectively today as geometrical optics, the rules constitute an extremely useful, though very approximate, model of light.
