Phase calibration of hydrophones: heterodyne time-delay spectrometry and broadband pulse technique using an optical reference hydrophone

Two hydrophone calibration techniques are presented which provide amplitude and phase of hydrophone sensitivity. Heterodyne time-delay spectrometry can be applied in the frequency range from 0.5 to 50 MHz to all common hydrophones but needs a standard to obtain absolute values. A pulse technique bet...
