The Method of Measuring Optical Spot of Radial Gradient Lens Based on Optical Probe Technique
基于光探针技术的自聚焦透镜光斑测量方法

Based on the theory of scanning probe microscopy, a novel method of measuring optical spot radial gradient lens utilizing optical probe technique is presented. After introduced system layout, the measuring principle,and analyzed optical spot scanning images of Japanese NSG radial gradient lens are given. The results are very useful for evaluating the imaging properties of radial gradient lens.
