Examples
- Specification for measuring depth of focus and best focus
焦深与最佳聚焦的测量规范 - Using gradient of digital image as criterion of focusing , different image grabbed on different lens position is compared , and lens motor is droved to the optimal position according to result of comparison
该方法利用图像的梯度和作为镜头聚焦的判据，对图像质量进行分析比较，根据比较结果驱动镜头运动直至最佳聚焦点。 - 3 . introduced the principle of phase - match and the optics characters of ktp 、 lbo and other nonliner crystrals , demonstrate the optimal focusing conditions . based on a detailed analysis , ktp and lbo are selected as shg and thg cystal , respectively
3 .简单介绍相位匹配原理和非线性晶体的选择介绍了一些紫外晶体的光学特性,并阐述了光束的最佳聚焦条件,经过分析和综合评价,选择了ktp和lbo分别作为倍频晶体及和频晶体。 - 2 . we design a configuration of frequency - doubler according to the optimum focus condition and the cavity stability condition | a + d | < 2 and optimize it based on " mode - matching " and " optimum coupling " . 99 . 96 % of optical impedance - match efficiency and over 95 % of spatial mode - matching efficiency are achieved eventually by using t = 10 % of input coupler in our experiment
( 2 )根据最佳聚焦条件和腔的稳定性条件( | a + d | 2 )对四镜环型倍频腔进行了设计，并分别从“模式匹配”和“最佳输入耦合镜透射率的选择”两方面着手对腔进行优化，在我们的实验中采用10的输入耦合镜，获得阻抗匹配效率为99 . 96 ，空间模式匹配效率高于95以上的模式。
