We perform heterodyned optical Kerr gated (HOKG) ballistic imaging of an object hidden behind a turbid medium using a femtosecond laser. The experimental results show that an optimum heterodyning angle should be selected to acquire the highest spatial resolution of the HOKG imaging system. The optimum heterodyning angle depends on the scattering parameters of the turbid media, and it decreases with increasing optical density or decreasing thickness of the turbid medium.
我们使用飞秒激光对隐藏在浑浊介质后的物体进行外差光学克尔门控（HOKG）弹道成像。实验结果表明，应选择最佳外差角度以获得HOKG成像系统的最高空间分辨率。最佳外差角度取决于浑浊介质的散射参数，并且随着浑浊介质的光学密度增加或厚度减小而减小。
