## Abstract The performance of the fiberβoptic displacement sensor with beamβthrough detection technique is investigated. The effects of lateral and axial displacements on the detected output voltage are investigated for various core's diameters of the sensor. The highest sensitivity is obtained at
Figure 3 Comparison of computed and reconstructed normalized Ε½ . Ε½ . electric field with SNR s 20 dB. a Real part, b imaginary part with SNR s 20 dB have no significant difference with the computed results in the frequency band 1α100 GHz, as shown in Figure 3. Therefore, the scattering model obtain
