This method consists of two steps. The first is to illuminate the object with a plurality of point sources each of which is mutually coherent with the reference source. All the points are contained within the pupil of the optical apparatus. The second step takes place after the hologram has been made in the manner mentioned. During the reconstruction, a mask is placed in the plane, conjugate to the plane containing the plurality of object-illuminating sources. An aperture in this mask is then moved to take positions to transmit only the light from one of the plurality of points at a time and to block the light from all the other points. The images thus detected are additive in intensity, simulating the plurality of illuminating point sources to be mutually incoherent.
该方法由两个步骤组成。第一步是用多个点光源照射物体，每个点光源都与参考光源相互相干。所有这些点都位于光学仪器的光瞳内。第二步在按照上述方式制作全息图之后进行。在重建过程中，在与包含多个物体照明光源的平面共轭的平面上放置一个掩模。然后移动该掩模中的一个孔径，使其每次仅透射来自多个点之一的光，并阻挡来自所有其他点的光。由此检测到的图像在强度上是相加的，模拟多个照明点光源相互不相干。
