近年来,调制传递函数 MTF 的测量方法,已成为检验物镜象质的主要方法。我们的任务是在同一台装置和在不同的装置上,对物镜的传递函数测量值和理论计算值进行比较,并且需要鉴定这些装置,特别是评价在这些装置上,调制传递函数的测量精度。因为测量装置的个别结构零件,存在着制造、装配和调整方面的误差,确定 MTF 的测量误差是一项复杂的任务。另一种方便的
In recent years, the modulation transfer function MTF measurement method has become the main method to test the quality of the objective lens. Our task is to compare the transfer function measurements of the objective with the theoretical calculations on the same device and on different devices and to identify these devices and in particular to evaluate the measurement accuracy of the modulation transfer function at these devices. Because of the manufacturing, assembly and adjustment errors of individual structural parts of the measuring device, it is a complex task to determine the measurement error of the MTF. Another convenient
