La configuración habitual de un arreglo para medir las aberraciones oculares, utiliza un haz infrarrojo, el cual es focalizado en la retina con el fin de que actúe como una fuente secundaria de radiación. La luz reflejada emerge a través del sist

We develop a new avenue to creating the optical spectrometer for the Guillermo Haro astrophysical observatory (Mexico), which combines specifically progressed prism spectrometer with modern acousto-optical approach in the frame of a joint instrument.

We consider physical conditions for realizing the Bragg regime of one-, two-, and three-phonon scattering of light in optically anisotropic crystalline materials. The exact and closed analytical models for describing these regimes are developed and s

The cornea contributes substantially to the performance of the human eye and obtaining the shape of the anterior corneal surface is crucial for ophthalmic applications such as the manufacture of contact lenses and visual laser correction. In this dir

The application of the wavefront sensors to measuring the monochromatic aberrations of the normal human eyes has given a new insight in the objective understanding of its performance. The resultant wavefront aberration function can be applied to eval

We show that an anisotropic grating with two alternate linear perpendicular states of polarization is transformed by free propagation, at 1 4 of the Talbot distance, into another grating with circular polarization states. Experimental results that ve
