| Zusammenfassung | An optical calibration technique is described, which allows the investigation of the frequency response of ultrasonic detectors up to a frequency of 50 MHz. This technique is applied to determine the transfer function of a metal-coated ultrasonic fiber tip sensor which is based on an interferometric measurement of the displacement using a Michelson interferometer. The transfer function is used to correct shock wave data which are, by this means, measured with a calibrated system. |
