WebView history. In mathematics, the Rayleigh theorem for eigenvalues pertains to the behavior of the solutions of an eigenvalue equation as the number of basis functions employed in its resolution increases. Rayleigh, Lord Rayleigh, and 3rd Baron Rayleigh are the titles of John William Strutt, after the death of his father, the 2nd Baron Rayleigh. WebThe terms k1 and k2 are sometimes described as constants, but in reality are the scaled or dimensionless resolution and DOF, respectively. The DOF Rayleigh equation can also be corrected for high numerical aperture effects. Example: The Rayleigh equations are frequently misused by lithographers who do not understand their limitations.
