Traditional optical fiber interferometry systems rely on complex optical path configurations, including reference and measurement arms, to maintain a phase difference. In contrast, in-fiber interferometers offer a more compact and efficient alternative for integration and miniaturization. While conventional fabrication methods, such as misalignment welding, have been widely used, they involve complex processes and inconsistent quality, limiting flexibility and adaptability to different testing environments. This study introduces an in-fiber dynamically modulable Mach-Zehnder interferometer (DMMZI) based on ultrasonic waves. The vibrations induced by ultrasonic waves create a periodic refractive index distribution within the fiber, leading to the formation of long-period gratings (LPGs). The ultrasonic waves propagate axially along the fiber, and the coupling of two waves at specified time intervals resembles the cascading of dynamic LPGs, resulting in the formation of a DMMZI. Theoretical and experimental investigations demonstrate that by adjusting the frequency, duration, and interval of the ultrasound, the characteristics of the interferometer can be effectively tuned. The strain response of the system has also been validated, showing that the DMMZI possesses excellent sensing capabilities and flexibility, making it suitable for various measurement scenarios and target parameters in future applications.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"192 ","pages":"Article 113564"},"PeriodicalIF":4.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to simulations, the laser pulse experienced a nonlinear amplification with the spectrum asymmetrically extending to the short wavelength side, mostly driven by the self-phase modulation and high excitation of the gain fiber at the output end.

The reference interferometer can obtain the information of environmental noise and system noise. The DBN is employed to construct a dynamic correlation model between the interference signal and vibration signals. By extracting multidimensional features, the model learns how six output interference signals are changed with vibration in measured environment. To further promote the performance of single DBN model, an ensemble learning method is used to learn the knowledge of five different DBN models. Experimental results demonstrate that in the range of 10 Hz to 1000 Hz, the ensemble DBN model can achieve vibration measurement with higher SNR. The proposed method can reduce background noise by 22.8 dB in 1 kHz vibration environment, and the SNR is 79.9 dB.

Subsequently, it integrates linear stretching to increase the dynamic range of color compensated image. Secondly, an adaptive gamma correction algorithm is used to enhance the overall contrast of the color-corrected image, and a multi-scale side window box filter (SWBF) technique is employed to improve its local details simultaneously. Finally, the stationary wavelet transform is used to decompose the enhanced images into low-frequency (LF) and high-frequency (HF) components. Perception fusion rules tailored to the different characteristics of each component are devised to improve the visual quality of the resultant image.
