Test images of a sector star versus radial and axial merit functions

The radial and axial point spread function (PSF) and the 3D modulation transfer function (MTF) were calculated to demonstrate the influence of phase only filters in classical optical imaging systems. The 3D line spread function (LSF) makes it possible to discuss the influence of the degree of cohere...
