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。

Employing computer to control optical scanners and lock-in amplifier to modulate gain and shift phase, a fluorescence phase-sensitive imaging system has been investigated for ruby and Ti-sapphire experimentally. The images with phase shift of π/12, π/4, and 7π/12 were obtained. The time resolution and the space resolution, as well as the practicality, of the system are analyzed.
