the focus. The zone plate has a primary focus, and an infinite number of secondary focuses. The path difference of waves from adjacent transparent areas to the main focus is equal to the radiation wavelength. The waves from the transparent zones arrive to the focal point in ...
1.It is an off axis, binary phase, Fresnel zone plate.低效取样光栅是激光取样技术的一种重要元件 ,它可以看成离轴的二相位的菲涅耳波带板。 2.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...
The use of a Fresnel zone plate as a coded aperture for imaging incoherent radiation such as gamma rays has been previously reported. The coded image is in many respects similar to a hologram and can be decoded or reconstructed with a coherent optical system. In this paper, the general theor...
