Paper Abstract

A laser opto-acoustic system for measuring 3-D objects surface topology has been described. The main principle of operation consists in excitation of a short acoustic pulse by irradiation of surface under test by short laser pulse and in measuring the time of acoustic pulse traveling to the detector. A laser pulse with nanosecond scale duration and liquid immersion medium with high enough sound speed was used to increase the measurement precision. The examples of system applications including aircraft turbine blade measuring have been presented.
