“…Recently, a low noise phase measurement of a fiber optic sensor conducted via weak value amplification is experimentally demonstrated to have a flat and wideband frequency response from 0.1 Hz to 10 kHz [20]. In addition, a WVA-enhanced hydrophone using a 0.8 meter long optical fiber was experimentally demonstrated [21], which was further improved to obtain a high-performance fiber optic interferometric hydrophone with high sensitivity and widefrequency response [22]. However in the absence of analyzing the amplitude-type noise effect, the feasibility for a more general case, such as applying longer optical fiber or other WVA schemes [23], is not yet clear.…”

Experiments based on a free-space platform have demonstrated that the weak-value amplification (WVA) technique can provide high sensitivity and precision for optical sensing and metrology. To promote this technique for real-world applications, it is more suitable to implement WVA based on an optical-fiber platform due to the lower cost, smaller scale, and higher stability. In contrast to the free-space platform, the birefringence in optical fiber is strong enough to cause polarization cross talk, and the amplitude-type noise must be taken into account. By theoretical analysis and experimental demonstration, we show that the optic-fiber-based WVA is robust in the presence of amplitude-type noise. In our experiment, even the angular misalignment on optical axes at the interface reaches 0.08 rad, and the sensitivity loss can be maintained at less than 3 dB. Moreover, the main results are valid to a simplified detection scheme that was recently proposed that is more compatible with the future design of optical-fiber-based WVA. Our results indicate the feasibility of implementing WVA based on optical fiber, which provides a possible way for designing optical sensors with higher sensitivity and stability in the future.

“…For reception, piezoelectric hydrophones can be constructed with polymers, such as polyvinyledine fluoride (PVDF), that enable them to provide an output voltage that varies according to acoustic pressure [12]. Besides PVDF, there are ultrasound sensors made with optical fibers [13][14][15][16][17][18][19][20][21][22].…”

“…To the best of our knowledge, there are no published works describing laboratory prototypes of an FOH system to measure liquid volumes and presenting results of accuracies and RMSE derived from machine-learning algorithms. There are publications describing the behavior of underwater optical coils, but they do not present results of using these coils to measure liquid volumes [16][17][18][19][46][47][48][49]. Ultrasound methods to determine multilayers of oil, emulsion, and water in oil tanks are demonstrated in [10,46,50] and show the advantages of FOH, such as contactless distance measurement, low costs, high precision, simple setup, and imperviousness to dusty and smoky environment.…”

“…Considering an FOH system as a new generation [15] and a primary application [40] for underwater acoustic sensors and underwater detection [19], the objective of this work is to present a prototype composed of optical fiber coils in the MI's sensor head, with an active stabilization mechanism driving another optical coil wound around a piezoelectric actuator in the MI's reference arm, and a software application that uses amplitudes and phases of detected acoustic signals to predict liquid volume by machine learning algorithms.…”

“…Although ∆φ may appear to be a stable measurand, the noise present on φ e can be so elevated that the measurand dφ M may become impossible to read [31,40]. More details about the MI working as an optical hydrophone for signal intensity (irradiance) and phase (homodyne or heterodyne) measurand detection can be obtained from other studies: [7,15,18,19,25,31,32,40,52,[54][55][56].…”

Sensing technologies using optical fibers have been studied and applied since the 1970s in oil and gas, industrial, medical, aerospace, and civil areas. Detecting ultrasound acoustic waves through fiber-optic hydrophone (FOH) sensors can be one solution for continuous measurement of volumes inside production tanks used by these industries. This work presents an FOH system composed of two optical fiber coils made with commercial single mode fiber (SMF) working in the sensor head of a Michelson’s interferometer (MI) supported by an active stabilization mechanism that drives another optical coil wound around a piezoelectric actuator (PZT) in the reference arm to mitigate external mechanical and thermal noise from the environment. A 1000 mL glass graduated cylinder filled with water is used as a test tank, inside which the sensor head and an ultrasound source are placed. For detection, amplitudes and phases are measured, and machine learning algorithms predict their respective liquid volumes. The acoustic waves create patterns electronically detected with resolution of 1 mL and sensitivity of 340 mrad/mL and 70 mvolts/mL. The nonlinear behavior of both measurands requires classification, distance metrics, and regression algorithms to define an adequate model. The results show the system can determine liquid volumes with an accuracy of 99.4% using a k-nearest neighbors (k-NN) classification with one neighbor and Manhattan’s distance. Moreover, Gaussian process regression using rational quadratic metrics presented a root mean squared error (RMSE) of 0.211 mL.
