M. Martinez-corral et al., One-dimensional iterative algorithm for three-dimensional point-spread function engineering, OPTICS LETT, 26(23), 2001, pp. 1861-1863
We present a new method with which to binarize pupil filters designed to co
ntrol the three-dimensional irradiance distribution in the focal volume of
an optical system. The method is based on a one-dimensional iterative algor
ithm, which results in efficient use of computation time and in simple, eas
y to fabricate binary filters. An acceptable degree of resemblance between
the point-spread function of the annular binary filter and that of its gray
-tone counterpart is obtained. (C) 2001 Optical Society of America.
