Paper Abstract

This paper presents a proposed application of the quantized fraction Fresnel zone plate (QF- FZP), a binary optics element, for increasing propagation distance of directed radiation beams. The design procedure and formula of QF-FZPs based on the vibration vector method are presented. If a QF-FZP of four quantized phase levels is used, the propagation distance of directed radiation beams can be prolonged 1.5 times further while the incident radiation beam maintains the same intensity. Finally, Fresnel-Kirchhoff diffraction theory is used for analyzing the axial intensity distribution of directed radiation beams diffracted by QF-FZPs.
