Abstract

It is well known that turbid medium such as fog or biological tissues causes light scatter. This phenomenon is known as major impediment for imaging and focusing of light. Thus it is important to understand the impact of the turbid medium on the light characteristics, namely intensity and phase distributions. In this work laser beam propagation through the scattering suspension of polystyrene microspheres in distilled water was investigated both theoretically and experimentally. We obtained the dependence of the wavefront aberrations on the particles concentration and shown the existence of high-order symmetric wavefront aberrations of the laser beam passed through turbid medium. The investigation showed that with the use of bimorph deformable mirror the wavefront aberrations of scattered light could be effectively corrected.
