Patent ID: 7516031

Claim:
A method for correcting a measured scattering pattern containing multiple significantly distant components and/or peaks for the effects of aberration influencing the component and/or peak shapes and/or positions, the method including: i) inputting a measured pattern f(2θ) as a function of a parameter 2θ representing the scattering angle, and calculating a representation of the measured pattern f(2θ) in a space for applying corrections; ii) obtaining a representation of an aberration function including a description of instrumental aberrations F inst depending on the parameter 2θ in the same space; and iii) performing deconvolution of the calculated representation of f(2θ) to create an aberration corrected pattern f corr (2θ) to reduce the effects of aberrations in representation of f(2θ), including performing the deconvolution point by point for different values of the parameter 2θ using for each value of the parameter 2θ a respective representation of the aberration function F inst for a respective value of the parameter 2θ.
