Retrobulbar neuritis, an inflamed optic nerve, but with a normal-appearing nerve head, is associated with pain and the other findings of papillitis. Pseudopapilledema is a normal variant of the optic disk , in which the disk appears elevated, with indistinct margins and a normal vascular pattern.
The figure shows the optical path of a Mirau-objective respectively a Mirau-interferometer. Reference beam (4 to 6) and object beam (7) have identical optical path length and can thus cause white light interference.
Mirajul Islam (Bengali: মিরাজুল ইসলাম; born 1 October 2006), commonly known as Miraj, is a Bangladeshi professional footballer who plays as a ...
Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials.
The rays refracted by a non-flat surface form caustics where many of them cross. Concentration of light, especially sunlight, can burn.The word caustic, in fact, comes from the Greek καυστός, burnt, via the Latin causticus, burning.
Optics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. [1]
Figure 1. The light path through a Michelson interferometer.The two light rays with a common source combine at the half-silvered mirror to reach the detector. They may either interfere constructively (strengthening in intensity) if their light waves arrive in phase, or interfere destructively (weakening in intensity) if they arrive out of phase, depending on the exact distances between the ...
