The angle between the maximum peak of radiated power and the first null (no power radiated in this direction) is called the Rayleigh beamwidth. The simplest way to define the width of a beam is to choose two diametrically opposite points at which the irradiance is a specified fraction of the beam's peak irradiance, and take the distance between them as a measure of the beam's width. An obvious choice for this fraction is ½ (−3 dB), … WebInterference of light is perhaps the most ubiquitous phenomenon in optical microscopy and plays a central role in all aspects of image formation. ... or the full width at half maximum; FWHM) are directly related to the properties and geometry of the point-spread function.
