High-speed laser scanning control system for confocal microscopy

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.
