摘　　要：利用光学设计软件ZEMAX模拟Wolter显微镜对点光源成像。在只考虑几何光学成像的条件下,分三种情况讨论:两曲面同轴共焦点,两曲面不同轴,两曲面同轴不共焦点,对点源通过Wolter系统成像分别进行了光线追踪模拟。通过模拟,定量给出了Wolter显微镜的焦深和景深,分析了处于不同视场点源所成的像,以及两个曲面不同轴时和不共焦点的情况下点源所成的像,得知Wolter显微镜对物像距的要求很严格,两曲面的不同轴度和两曲面的不共焦点对成像影响非常大,这些模拟结果为Wolter显微镜的成像分析提供了依据。The optical design software ZEMAX is used to simulate the imaging of a point source for Wolter microscope.Considering the imaging of geometrical optics only,three instances are considered,including the two surfaces coaxial and cofocal,non-coaxial,and coaxial but not confocal.The imaging of a point source is discussed respectively.The depth of focus and the depth of field are given.The imaging of a point source in different fields is also analyzed.It is concluded that Wolter microscope is very strict with the object distance and image distance.The influence of the two surfaces＇ non-coaxiality and non-confocality is much great on imaging.These results provides basis for imaging analysis of Wolter microscope.
