Strehl Ratio

The Strehl ratio is a measure of the quality of optical image formation.

The Strehl ratio equals the exponential of -4\[Pi] squared times the root mean square deviation of the wavefront squared divided by the wavelength squared.

Formula

QuantityVariable["S", "StrehlRatio"] == E^((-4*Pi^2*QuantityVariable["σ", "Length"]^2)/QuantityVariable["λ", "Wavelength"]^2)

symbol description physical quantity
S Strehl ratio "StrehlRatio"
λ wavelength "Wavelength"
σ root mean square deviation of the wavefront "Length"
