WebThe circumstances that lead to combustion instabilities have been described by Lord Rayleigh in the so-named Rayleigh's criterion [3, 4]. ... This can be an undesirable … 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.
WebNov 13, 2015 · The definition of focus is somewhat subjective, but a standard depth of field "unit" is often defined as half the axial Rayleigh unit: d = lh/(NA) 2. Another criterion that is … Web7. The camera must simultaneously focus on the object surface and the remote screen pattern (sinusoidal fringes). This depth-of-field problem requires a trade-off between angular uncertainty and lateral resolution 51.
