Spot diagrams and the synthesized images of the Siemens star object obtained by an image synthesizer in which the above spot diagrams obtained on a cathode-ray tube were used as the light sources, were compared with the aberration curves and the optical traasfer function of the same manufactured lens. The comparison was performed on several field angles and image planes. Systematic comparison of these results gives us versatile information about the image quality of the lens and enables us to understand the mutual relations existing between them. For instance, spurious resolution and heavy deterioration of the images were observed on the synthesized images when there were negative components in the transfer function. Also, it was found that there was an intimate relation between the above defects of images and the spread of the spot diagrams. Next we set the model lenses based on the above one. In these model lenses, certain aberrations were intentionally altered slightly from the initial values without changing the other aberrations. As for these model lens systems, comparisons similar to the above were performed in order to examine the effect and the way each aberration contributed to image quality.
将阴极射线管上获得的上述点列图用作光源，通过图像合成器得到的西门子星点物体的点列图和合成图像，与同一制造镜头的像差曲线和光学传递函数进行了比较。在几个视场角和像平面上进行了比较。对这些结果进行系统比较，为我们提供了关于镜头图像质量的多方面信息，并使我们能够理解它们之间存在的相互关系。例如，当传递函数中存在负分量时，在合成图像上观察到虚假分辨率和图像严重退化。此外，还发现上述图像缺陷与点列图的扩展之间存在密切关系。接下来，我们基于上述镜头设置了模型镜头。在这些模型镜头中，某些像差在不改变其他像差的情况下有意从初始值略有改变。对于这些模型镜头系统，进行了与上述类似的比较，以检查每种像差对图像质量的影响和作用方式。
