WebDespite its approximate nature, Rayleigh's 1/4 wave criterion was the corner stone in: (1) determining the effect of aberrations on image quality, and (2) defining the appropriate tolerances. Pretty much neglected for decades, it was given due attention in the early 20th century, particularly in the work of Joseph Conrady ( Applied Optics and Optical Design , … WebObviously, the standard deviation of the Rayleigh distribution is just the square root of the Rayleigh variance. Skewness of the Rayleigh distribution: 2 * (π - 3) * √ (π / (4 - π)³) …
