Rayleigh depth of focus
WebNov 1, 1999 · Abstract Many different techniques are used for the calculation of Rayleigh optical depth in the atmosphere. In some cases differences among these techniques can … In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh length is particularly important when beams are modeled as Gaussian beams.

WebThe definition of focus is somewhat subjective, but a standard depth of field "unit" is often defined as half the axial Rayleigh unit: d = λη/(NA) 2 Another criterion that is occasionally utilized instead of the axial Rayleigh criterion is the full width at half maximum ( FWHM ) of the central bright region of the point spread function. WebThis point, usually at some depth within the Earth, is called the focus, or hypocentre. The point at the surface immediately above the focus is known as the epicentre . Love and …
