Laser beam focusing through the scattering medium using 14-, 32- and 48-channel bimorph mirrors

Efficiency of the laser beam focusing through the scattering medium with known concentration values was numerically investigated. We used the response functions of 3 kinds of bimorph deformable mirrors - with 14, 32 and 48 electrodes. The algorithm for numerical correction were programmed. The obtained results shown that 14 electrodes (2 rings) are not enough to compensate for the distortions, produced by the scattering medium with the given concentration values.
