- 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。 - 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。 - Simplifying experimental setting , shorting scan time , making the most of radiation dose and avoiding focus error , this method has significant value to real - time medical diagnosis
从而大大简化了扫描装置，提高了扫描速度，更有效地利用了放射剂量，并避免了对焦误差，对于医学实时诊断具有重要价值。 - We acquired best restoration of defocus images using one blurred image , and estimated the focused position according to radius of blurred circles at two different lens positions , the focus error was less than 5 %
利用单幅图像，用图像恢复的手段得到了准焦位置图像的最佳恢复；利用在两个位置所得图像，用模糊圆半径估计出准确对焦位置，对焦误差小于5 。 - This paper analyses the critical angle method that often use in focus detected . we receive two relations , the first relation between refractive index of the critical - angle prism and focus - error signal ; the second relation between numerical aperture of object lens and out - of - focus error signal
