Houston proposes thus to use the full-width at half-maximum (FWHM) of the diffraction pattern of a point source (being the PSF of the imaging system), to quantify the lateral resolution [14] because more useful in practice and also applicable to diffraction patterns that do not fall shutterfly create photo book
