The figures are as follows:

Fig. 2     OTDR: The OTDR of the ultra low-loss enhanced backscattering (ULEB) fiber that contains 50 point reflectors. 
	   The vertical axis is plotted in log scale to better shows the reflectance of the point reflectors

Fig. 3(a)  Waterfall Plot: 3D representation of vibration along the sensing fibre known as waterfall plot.
	   
Fig. 3(b)  Spectrogram: 3D representation of vibration along the sensing fibre in frequency domain a.k.a spectrogram.

Fig. 3(c)  Spatial resolution: A 2D cross section of the spectrogram plot at a fixed frequency as a function of distance showing the spatial resolution.

Fig. 4(a)  ASD: The amplitude spectral density of the DAS system at three adjacent channels on ULEB fibre.

Fig. 4(b)  Linearity: A linear relationship between voltage applied to the PZT and DAS reading.
