Testifying secondary maximum among slits interference item of grating diffraction is symmetrical with Fresnel Zone Plate Method;

We educe minimum and secondary maximum stripe location formula of grating diffraction with the method of Fresnel Zone Plate Method.

Fresnel Zone and seismic wave field in the fracture-vug reservoir.;

Study of non-zero offset Fresnel zone;

Two dimensional common reflection surface stack based on the Fresnel zone;

Design and analysis of the Fresnel zone plate applied in the refractive-diffractive hybrid imaging system with the short focus length;

By using three-time lithography,a combination structure of Fresnel zone plate and plane gratings with 8 phase level steps can be prepared on a quartz substrate by micro-optical element fabrication technology according to Fresnel diffraction theory.

By using Fresnel zone plate′s focusing function, and combini.

It is an off axis, binary phase, Fresnel zone plate.

In order to verify the effect of Fresnel zone plate convoluting with the object wave function,we used the nonmovement convolution device to realize the processes of convolution and deconvolution between FZP and the object wave function.

Using the theory of binary optics to improve the Fresnel zone plate, one can raise its diffraction efficiency greatly.
