Adrian Carbajal-Dominguez, Jorge Bernal, Alberto Martin-Ruiz, Gabriel Martínez Niconoff

摘要:

介绍了一种产生具有可控空间部分相干特性的J0贝塞尔光束的方法。计算了环形区域上离散多个源点的远场衍射。数值计算和实验检测了在几个旋转角度产生的不同衍射场的平均值。理论和实验结果表明,在这种特殊情况下,当光束的点数趋于无穷大时,J0贝塞尔光束是一个极限,相应的复相干度也是点数的函数。

英文摘要:

An alternative method to generate J0 Bessel beams with controlled spatial partial coherence properties is introduced. Far field diffraction from a discrete number of source points on an annular region is calculated. The average for different diffracted fields produced at several rotation angles is numerically calculated and experimentally detected. Theoretical and experimental results show that for this particular case, J0 Bessel beam is a limit when the number of points tends towards infinity and the associated complex degree of coherence is also a function of the number of points.
