WebFeb 1, 2012 · A comparison of the Rayleigh range between the two types of definitions (defined by the mean-squared beam width and the effective radius of curvature) is studied analytically and numerically, where the propagation of partially coherent beams both in free space and in atmospheric turbulence are considered. It is shown that the two types of the ... Webrayleigh relation的中文翻译，rayleigh relation是什么意思，怎么用汉语翻译rayleigh relation，rayleigh relation的中文意思，rayleigh relation的中文，rayleigh relation in …

The mode in the Near Field often has a so-called “bullseye” pattern to it. In the Rayleigh Range, the mode can be controversial.
