本工作采用了圆孔采样的连续型模型对所设计的几种颗粒有序排列的照相层相应的影像层的颗粒度进行了计算机模拟测量。测量的结果表明,与方孔采样的结果不同,圆形采样孔孔径尺寸的微小变化所引起的颗粒度测量值的波动小,测量值比较稳定。此外,各种颗粒有序排列图案的试样在不同的显影密度下几乎具有相同的结果。 In this work, a continuous model of circular hole sampling was used to simulate the graininess of the corresponding image layer of several orderly arranged photographic layers. The measurement results show that, unlike the square hole sampling results, the variation of the particle size measurement caused by the small change of the aperture size of the circular sampling hole is small, and the measurement value is relatively stable. In addition, the samples with various particle ordered patterns have almost the same result at different development densities.
