By ray-tracing methods we have investigated various configurations of Wolter I type x-ray telescopes. For the criterion of image quality the shape of the line spread function has been chosen. The angular resolution we find herewith in a large region of the basic parameters appears to be more than three times higher than results from the rms blur circle criterion. We have concluded that in most cases of practical interest the paraboloid-hyperboloid combination has to be preferred to the Schwarzschild system. In all cases it is possible to find a solution giving an extra improvement of the angular resolution with a factor between,2 and 4 when we describe the mirror shapes with polynomials.
通过光线追迹方法，我们研究了沃尔特I型X射线望远镜的各种配置。对于图像质量标准，选择了线扩展函数的形状。我们据此在基本参数的很大范围内发现的角分辨率似乎比均方根模糊圆标准的结果高三倍以上。我们得出结论，在大多数实际感兴趣的情况下，抛物面-双曲面组合比施瓦兹希尔德系统更可取。在所有情况下，当我们用多项式描述镜面形状时，都有可能找到一种解决方案，使角分辨率额外提高2到4倍。
