The multipoint optical system, based on fast optical elements, for precise laboratory measurements of vibratin of turbine blades under rotation was proposed in the IT AS CR. The optical system registers time passages of the blades. The paper describes optical sensor, test setup with measuring and excitation systems, results of numerical simulations and the first experimental results on the bladed wheel under rotation.
