It is … Webforgotten. While equation (6) would apply to any small pattern of lines and spaces (that is, any pitch applied to equation (2) so that only the zero and first orders go through the lens), Lord Rayleigh essentially looked at the extreme case of the smallest pitch that could be imaged – the resolution limit.
WebMar 1, 2006 · The resolution limit of Rayleigh's criterion is thought to arise because of the finite width of the central peak of the point-source image, i.e., the point spread function . …
