Abstract

We inject a laser beam into a tank filled with a milk-water emulsion and measure the intensity distribution of the scattered light. As we change the concentration of the milk, we observe a nontrivial change in the light intensity as a function of the detector position. We analyze the light on and parallel to the input beam direction, as well as the scattered light in the transverse direction. The nonmonotonic scaling of the intensity as a function of the concentration and the position is also predicted by Monte Carlo simulations. With a doubling of the concentration, the detected light along the optical axis decreases globally, whereas the reflected light decreases or increases depending on the location of the detector.
