利用计算机控制振镜进行光束扫描，用锁相放大器进行增益调制与相位调节，最后再用计算机重建图像，实现钛宝石和红宝石的相位成像。分别完成了激发光和荧光相移为π／１２、π／４和７π／１２的成像，分析了系统的时间分辨率和空间分辨率，提出了实用化发展的方向 The use of computer-controlled galvanometer beam scanning, with a lock-in amplifier for phase modulation and gain adjustment, and finally rebuilt the computer image to achieve the phase of titanium and ruby ​​ruby ​​imaging. The imaging of excitation and fluorescence phase shifts of π / 12, π / 4 and 7π / 12 were completed respectively. The temporal resolution and spatial resolution of the system were analyzed. The direction of practical development
