The promising method of light beam phase control based on beam transmission through the medium layer perturbed with acoustid wave generated by the lateral surface “lens”, requives the exact calculation of the acoustic field inside cylindrical cavity of the “lens”. We use the comm program Comsol for calculation and demonstrate that for the axial symmetric cylinder, which was used as a test object, the calculated distribution very close coinsides with theoretical form resulted from acoustic equations solutions.
