Truncated apodizers for engineering the point spread function of optical systems

Efficient truncated apodizers are presented to modulate the point spread function (PSF) of the optical system suffering from a high level of primary aberrations. It has shown that the resolution of the optical system is increased with the selected amount of apodization β (a shaded region across the aperture function) and the central obstruction ratio ε. Further, it is manifested by a narrow prime lobe, and minimal sidelobes in the resulting PSF intensity profile curves and the presence of a steep dip in the resultant composite light distributions of two intersecting point sources are mutually incoherent.
