本文提出了一种新的变焦透镜结构，其工作带宽为1kHz。开发了两种原型来验证该结构。通过频率响应测量确认了1 kHz带宽。一个原型是应用于共焦激光扫描显微镜的轴向高速扫描。成功地实现了在1 ms内对微观物体的深度信息测量和自动聚焦以保持对随机移动物体的聚焦。
This paper proposes a new structure of variable-focus lens aimed at 1 kHz bandwidth. Two kinds of prototypes are developed to validate the structure. The 1 kHz bandwidth is confirmed by the frequency response measurements. One prototype is applied to the axial high-speed scan of a confocal laser scanning microscope. Depth information measurements of a microscopic object in 1 ms and automated focusing to keep the focus on a randomly moving object are successfully achieved.
