Illustration of angular devition in a prism. Angular deviation of a prism depends on the prism angle α, the refractive index, n, and the angle of incidence θi. Minimum deviation occurs when the ray within the prism is normal to the bisector of the prism angle. For small prism angles ...
Ray-tracing formulas for refraction and internal reflection in uniaxial crystals. Formulas for the calculation of the direction cosines of refracted and internally reflected rays in anisotropic uniaxial crystals are presented. The method... G,Beyerle,I,... - 《Applied Optics》 被引量: 51发表: ...
A general method for dealing with the propagation of waves in homogeneous anisotropic media is presented. The formulas were derived and applied to determine the reflected and transmitted waves resulting from a plane wave obliquely incident at an interface between two anisotroptic media with arbitrarily...
A new formalism is presented concerning the dynamics of X-rays in crystals. It is based on Takagi's equations and Fourier optics; it also offers an alterna... G Mana,F Montanari - 《Acta Crystallographica》 被引量: 6发表: 2010年 Generalized Laue dynamical theory for x-ray reflectivity at...
Besides that, equivalent conservation laws (divergent identities) were found for families of rays and families of wavefronts in terms of their geometric characteristics. Thus, the geometric essence (interpretation) of the conservation laws obtained for the 2D eikonal equation was found. In this ...
Mirage occurs when a ray of light falls on earth by travelling from the top of a tree or sky; it gradually deviates away from the normal. We know that total internal reflection exists when the angle of incidence becomes greater than the critical angle. So this generates mirage in hot deser...

In the present study, ray tracing was employed to model different eyes and adjust the theoretical positions of the IOLs to achieve emmetropia. To our knowledge, this is the first instance of using this tool for such a methodology and purpose. FromFigure 2a,b, a strong correlation was found...
