Abstract

The ability to focus laser beam with wavelength 0.65 um through the multiply scattering suspension of polystyrene microspheres, diluted in distilled water, was investigated. Experimental setup, contained the Shack-Hartmann sensor for measurements of the local slopes of the Poynting vector, the CCD camera for estimation of the far-field focal spot’s intensity and the bimorph mirror with 48 electrodes was built. Numerical and experimental investigations of focusing efficiency was carried out also.
