摘要
A method for the automatic correction of the in the determination of the flat displacement of two digital images to each other occurring errors caused by deformations of the system of an optical correlators of the type jtc, which the two for the correlation analysis necessary optical fourier transform in one and the same optical fourier - processor to carry out, wherein the image of the first fourier transformation as input image of the second fourier transformation in the light modulator of the optical fourier - processor is fed, characterized in that the resulting image of the first fourier transformation before being fed into the light modulator as input image of the second fourier transformation about its horizontal or vertical axis is mirrored.
