与使用丝状测微器或经纬网测量通过光学系统传输的图像相比，图像分割原理具有重要的优点。本文叙述了将这一原理应用于显微镜的方法。理论分析表明，应能达到艾利盘半径的十分之一的安装精度，并证明在一定条件下不会引入系统误差。文中描述了实验，证实了这些结论，并说明了该仪器的一些应用。
The image-splitting principle offers important advantages over the use of filar micrometers or graticules for the measurement of an image transmitted through an optical system. A method for applying this principle to the microscope is described.Theoretical considerations indicate that a setting accuracy of one-tenth of the radius of the Airy disk should be attainable, and it is shown that under certain conditions no systematic error is introduced. Experiments are described which substantiate these conclusions and illustrate some applications of the instrument.
