摘要:
根据各向异性高斯-谢尔模型光束在空间的传输公式,推导出小孔处的光强表达式,并依据此公式对实验进行数值模拟.结果表明,x和y方向的相干度变化,以及光束偏心率的大小都直接影响着归一化曲线的峰-谷间差值ΔTp-v的大小.在一定偏心率下,ΔTp-v随着相干度的增大而增大; 而在相同相干度下,偏心率的增大导致会ΔTp-v的减小.
Abstract:
Based on the transmission expression of anisotropic Gaussian Schell-model beam in free space,the expression of the optical intensity at the hole is derived,and the experimental results are also numerical simulated.The results show that the changes of spatial degree of coherence in x and y oriention and the ellipticity influence the tolerance between peak and valley.When the ellipticity is a constant,the tolerance is getting bigger with the increment of spatial degree of coherence.With a definite value of spatial degree of coherence the tolerance will decrease with the increment of ellipticity.
