WebThe required energy resolution is specified in terms of the spectral resolving power, R ≡ λ/δλ, where δλ is the resolution in wavelength defined usually in terms of the Rayleigh criterion. One of the main data products required in astrophysics is the velocity along the line of sight (radial velocity) obtained through measurement of the wavelength of a known spectral … WebThe Rayleigh criterion for resolution is met when the maximum intensity of one point spread function overlaps the first minimum of the other. For two points emitting at the same wavelength, this separation distance corresponds to the radius (or peak-to-minimum distance) of the central bright region of a single point spread function. http://www.lithoguru.com/scientist/litho_tutor/Tutor44%20(Feb%2004).pdf smart lights ge

"WebWhen two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA. In cases where two adjacent Airy patterns become closer to each other than in the Rayleigh criterion, the separation is known as the Sparrow limit, which is given by the equation: D = 0.47λ/NA " - Rayleigh's criterion for resolution
