Modulating the Amplitude of Scattering light for Focusing
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.
