摘要
本文推导了部分相干光在经过环形孔径之后,远场轴上点的光谱S(ω)与环形孔径处光的光谱S^(0)(ω)之间的关系。数值计算结果表明,S(ω)不仅依赖于S^(0)(ω),而且还与环形孔径处光的相干性以及环形孔径的参数有关。
The relation between the on-axis spectrum in the far field and the spectrumat the annular aperture is derived when partially coherent light passes throughan annular aperture, The calculated results show that on-axis spectrum in thefar field is not only dependent on S^(o)(ω), but also on coherence at the annularaperture, and the parameters of the annular aperture.
