共聚焦显微镜激光高速扫描控制系统设计及实现

摘要

Based on the traditional optical scanning and the effective combination of a high-frequency resonant scanner and a galvanometer scanner, a novel high-speed laser scanning method with sampling rate of 4M/s was proposed. The hardware platform of control system was built, the PC-client and microcontroller software were designed. The experimental results prove that the control system is rapid and stable, can realize real-time confocal scanning imaging.%在传统光学扫描方法基础上,有效地将检流式与共振式光学扫描振镜结合起来,提出一种速度可达4 M/s采样率的高速激光扫描方法,并基于单片机系统设计搭建了系统控制硬件平台,编写了上位机端和下位机端应用软件.实验结果表明:该控制系统扫描速度快,性能稳定可靠,能够应用于共聚焦显微镜,实现实时扫描成像.
