| Abstract: | Based on the unified theory of coherence and polarization,Electromagnetic Gaussian Schell-model beam was taken as an example to study the transmission properties of random electromagnetic beams diffracted by Fresnel zone plates,the influence of correlation length,the degree of polarization of incident light,and the max radius number of zone plates on the light intensity and the degree of polarization.It is shown that the coherent property and the max radius number of zone plates will influence the focusing ... |
