通过控制金属的沉积，在真空中蒸发，可以定量地改变反射表面的形状。介绍了计算屏的理论和实验技术。对一个12英寸的球面镜进行了多次抛物化，得到了0.05波长范围内的完美表面。一个558英寸的球面镜已经被抛物线化，光轴在其外围之外。一个有缺陷的抛物面镜被纠正了向上和向下的边缘。一个凸球面次镜被双曲线化。讨论了该方法的局限性和可能的应用。
It is possible to change the figure of reflecting surfaces quantitatively by controlled deposition of metals, evaporated in vacuum. The theory for calculating screens and the experimental technique are described. A spherical 12-inch mirror has been repeatedly parabolized, obtaining a surface perfect within 0.05 wave-length. A 558‐inch spherical mirror has been parabolized with the optical axis outside of its periphery. A defective parabolic mirror was corrected for turned up and down edges. A convex spherical secondary mirror was hyperbolized. The limitations and possible applications of the method are discussed.
