Paper Abstract

The image quality criteria based on the MTF of the image-forming instrument are faced with a practical problem when they are used for evaluating on-axis and off-axis samples together. For off-axis samples it is necessary to average the tangential and sagittal sections and to compare the result with the single on-axis MTF curves. A convenient solution to this problem is to consider the actual two-dimensional MTF. A simplified method for relating the one dimensional sections which are usually measured (tangential and sagittal) to the corresponding real two-dimensional function is given.
