Sensitivity | Linearity | Frequency response | Directivity | Stability | Temperature sensitivity Linearity Figure 5 Linearity of optical fibre hydrophone. Predicted curve is based upon measured acoustic phase sensitivity of 0.075 rad/MPa and the assumption of a low finesse Fabry Perot sensing cavity. The dotted vertical lines shows the acoustic pressure at which the sensor nonlinearity becomes 5% and 10%.[4] |
