In practice, however, the FWD should not be indefinitely increased because the number of photons converted into electrons is limited by the brightness of the light source. Additionally, the sensitivity enhancement is not significant above a certain ...

High-resolution Measurement of Refractive Index Based on Resonant Tunneling Effect
... Obviously, such a PBG may be viewed as a perfect mirror and is particularly useful for constructing the resonant cavities in the optical region, and only the resonant frequencies can be captured by this cavity. We can conjecture that the resonant frequency of the sharp peaks would shift when the ref ...

Optical aberration
.svg?width=300)
An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
