... However actual images are not monochromatic, but polychromatic. It turns out that under narrow band conditions (as is the case of imaging systems) one can consider the amplitude impulse response to be approximately constant (hλ,F(u,v) hF(u,v)). Even so, under polychromatic incoherent illumination ...

Confocal microscopy with a volume holographic filter
... The pinhole preceding the detector in a confocal microscope is a shift-variant optical element. On-axis in-focus point-source objects are imaged exactly inside the pinhole and give maximal intensity. An out-offocus object, even when it is on axis, is equivalent to an extended source on the input foc ...

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.
