Bz. Dong et al., ITERATIVE OPTIMIZATION APPROACH FOR DESIGNING AN AXICON WITH LONG FOCAL DEPTH AND HIGH TRANSVERSE RESOLUTION, Journal of the Optical Society of America. A, Optics, image science,and vision., 13(1), 1996, pp. 97-103
An iterative optimization approach for designing the phase of the unif
orm-intensity axicon is presented that is based on the general theory
of amplitude-phase retrieval in optical systems. We extend previous th
eoretical formulas to deal with the linear imaging system with multipl
e output planes. We carry out numerical simulation calculations for de
signing the axicon for cases of both uniform and Gaussian beam illumin
ations. The numerical results are in good agreement with the desired p
erformance of the axicon, for instance, with considerable uniformity a
nd smoothness of the on-axis intensity and energy flow as well as with
high lateral resolution. The influence of phase quantization on the d
esigned result is also investigated. (C) 1996 Optical Society of Ameri
