The interrelation of various image parameters such as point-spread function, line-spread function, edge response, flux passing through hole, flux passing through slit, and the spatial-frequency response is demonstrated. These image parameters are computed from the point-spread function in presence of aberrations and diffraction. The point-spread function is first calculated for varying amounts of spherical aberration, coma, astigmatism, and coma+astigmatism using the Zernike–Nijboer theory and then the other parameters are computed. The data are obtained for different focal positions. A discussion of method of computation of all these integrals on a Univac-1105 computer is included along with an analysis of errors.
