    Two-point Resolution of the Annular Aperture Imaging System under the Partially Coherent Illumination

      摘要
    • 摘要: 在部分相干光照明下的环孔成像系统,对两个点物分辨,按照Sparrow判据作了研究.将两个点物的分辨,作为两个参数的函数,其一为照明光的空间相干条件,其二为环孔中心阻挡进行了讨论.对于像面上两个点像的间隔与物面上两个点物的间隔的比值,以及像面上峰值强度与物面上峰值强度的比值,分别作了分析.

       

      Abstract: Two-point resolution with partially coherent light has been investigated in the annular aperture imaging system by using the Sparrow resolution criterion. The resolution is discussed as a function of two parameters. the spatial coherence condition of illumination and the central obstruction of an annular aperture. The ratio of the measurable to the real quantities of the point separation and the ratio of the measurable to the real quantities of the peak intensity are also analysed respectively as functions of the above two paramenters.
