Abstract
We propose an iterative algorithm for computation of the radial phase function of an optical element (focusator), which formates the light segment along the optical axis and is characterized by a given length and the required intensity distribution on the segment. The algorithm is also applicable to computing the multi-focal lens so that the focusator is capable of focusing into a set of longitudinal light segments.
