Reflection of lightAn ancient optics problem of Ptolemy, studied later by Alhazen, is discussed. This problem deals with reflection of light in spherical mirrors. Mathematically, this reduces to the solution of a quartic equation, which we solve and analyze using a symbolic computation software. ...

摘要: This paper presents a concentric objective consisting of two spherical mirrors. The optical layout of the objective provides a process of repeated reflection of a pencil of light rays from the two mirrors. Several versions of the design are considered in which four aberrations are absent....
Light - Reflection, Refraction, Total Internal: One interesting consequence of the law of refraction is associated with light passing into a medium with a lower index of refraction. As previously mentioned, in this case light rays are bent away from the
Mirror, any polished surface that diverts a ray of light according to the law of reflection. The typical mirror is a sheet of glass that is coated on its back with aluminum or silver that produces images by reflection. The mirrors used in Greco-Roman ant
The selective Bragg reflection by natural crystals is limited to energy commonly larger than about 2 keV photons. Below this energy the total reflection mirror was the only optical device to reflect and focus wavelengths shorter than the far UV until the development of adapted interferential mirrors...
(1964) where two spherical mirrors are separated by less than twice their (equal) focal lengths. The beam enters through a hole in one mirror, the reflected beams trace an elliptical or circular pattern on both mirrors, and the laser exits the cell through the entrance hole, though at a ...
