- The influence of aberration on measuring sensitivity in critical - angle method of total reflection for focus error detection was described
摘要分析了在临界角方法探焦技术中像差对测量灵敏度的影响。 - Before the angle is less than the critical angle , the reflect - coefficient is real number , when the angle reaches the critical angle , it is a complex number
入射角度到达临界角时，波在界面发射全反射。此时，反射系数不再是实数，而是复数。 - The relative phase shift between s - and p - light is a function of the incident angle , and changes highly with the incident angle in the vicinity of the critical angle
S光与p光的相对相位差是入射角的函数,当入射角在临界角附近变化时,相对相位差会随着入射角高灵敏度变化。 - We simulate the practicality system to experimentalize , obtain the relation between defocus and focus error signal , make it a condition that na = 0 . 625 and n = 1 . 7979
并模拟实际系统，实验得出当临界角棱镜的折射率n = 1 . 7979 、物镜的数值孔径na = 0 . 625时，离焦量与离焦误差信号的关系曲线。 - The theoretical expression of the critical angle is acquired , showing that it rises with the increase of the depth and period of modulation of refractive index . also , it increases as the beam width decreases
从理论上得到了该临界角的表达式,它随折射率调制周期、调制深度的增加而增大,且光束越窄临界值越大。
