Rayleigh criterion example
WebFeb 7, 2015 · The limit can be calculated from the Rayleigh criterion, given by R l = 0.61×λ/NA, where λ is the wavelength of the light from the sample, and NA is the numerical aperture of the imaging lens, given by NA = n×sin α. WebThe Rayleigh criterion for the diffraction limit to resolution states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other (see Figure 10.26 (b)). The first minimum is at an angle of size 12 {θ=1 "." "22"λ/D} {} so that two point ...

The most commonly used criterion to assess the stability of a thermoacoustic system, such as a gas turbine combustor or a rocket motor, is the Rayleigh criterion (Lord Rayleigh 1878).This criterion states that the acoustic energy increases when the heat-release rate is sufficiently in phase with the acoustic pressure that the work done …
