光束通过生物组织白色涂料等散射介质后将发生散射，实现对散射光束进行整形和控制具有重要的意义。使用振幅调制实时反馈的方法，对入射到散射样品的相干光的振幅进行预调整，探测器实时读取散射光斑数据作为反馈依据，以此调制空间光调制器上的对应区域，进一步补偿由散射介质引起的振幅失调。实验结果表明，目标位置光强得到显著增加，其能量平均值是调制前散射区域能量平均值的11倍。

Light will be scattered when passes through turbid media such as white paint or human tissue. It is of great significance for modulating and controlling the scattering light. The real-time amplitude modulation and feedback method is used to compensate the amplitude disorder produced by the turbid media. The light intensity of a certain area can be strengthened by introducing a pre-modulation on the incident light. According to the real-time feedback data from the detector, the amplitude disorder can be better compensated by controlling the amplitude of light on certain area of the spacial light modulator. The experimental result showes that the modulated intensity can be 11 times that without modulation.
