    摘要: The invention relates to a method for automatically correcting mechanical deformations of optical correlators and to a self-correcting optical correlator for use in the optical correlation analysis of two digital images, which allows the displacement of the images in relation to one another on the image plane to be determined in realtime. The invention uses the method for automatically correcting the errors of optical correlators, which are caused by deformations of the system and occur during the determination of the plane displacement of two digital images in relation to one another. The method is characterised by a vertical or horizontal reflection of the spectral image, the determination of the plane displacement of the images to be analysed in relation to one another at half the distance between the correlation points, the use of only one part of the pixels of the spectral image for the second transformation step and the superimposition of the images to be analysed with a calibration pattern. A JTC optical correlator is used to implement said method.
