Abstract

In this work the integral resolutions for methods Knox-Thompson and triple correlation of image intensity are investigated. That variant of realization of methods Knox-Thompson and triple correlation of image intensity is considered, when the shift of spectra of the image is made on some fixed spatial frequency. In this case the integral resolution of a method is possible to define as the integrated form from its optical transfer function on current spatial frequency. It is shown that to increase of value of fixed shift of spatial frequency there is the monotonous decrease of the integral resolution of system 'the turbulent atmosphere - telescope' for both methods. It is marked, that the integral resolution of a method of triple correlation of the image intensity is higher than the integral resolution of a Knox-Thompson method, and the integral resolution of a Knox-Thompson method always is lower, than integral resolution of a Labeyrie method.
