本文讨论了光电阴极光学监测装置的光学系统结构,对造成光学系统光能损失的因素作了分析,提出了开孔反射镜的改进方案;同时对改进前后的光学系统透光率进行了比较。开孔反射镜的孔洞造成了光能损失,用面积反射率(?)表示反射镜的有效光能;并将影响其数值的各元件间尺寸关系用公式表示。本文还对斩光器的结构尺寸与光脉冲的颇率、波形的关系进行了讨论。
In this paper, the optical system structure of optical cathode optical monitoring device is discussed. The factors that cause the loss of optical energy in the optical system are analyzed. An improved scheme of aperture mirror is proposed. At the same time, the transmittance of the optical system before and after the improvement is compared. The aperture of the aperture mirror causes the loss of light energy, and the area of reflectivity (?) Indicates the effective light energy of the reflector; and the relationship between the dimensions influencing the numerical value is expressed by the formula. The paper also discussed the relationship between the structure size of chopper and the pulse rate and the waveform of light pulse.
