Abstract

Experimental investigations of visible laser radiation focusing through a scattering medium using LCOS-SLM with the resolution 1920x1080 was performed. Optical depth of the scattering medium was varied from 1 to 10, anisotropy factor was equal to 0.9. According to the principle of similarity the medium with such parameters can be considered as an equivalent to the layer of the mid-density fog with the length from 300 m up to 5 km. Experimental investigations of the focusing improvement have demonstrated that it is possible to decrease the diameter of the focal spot by 5-13%.
