Polyurethane foam is a kind of polymer composite material. The foaming turgidity and reaction temperature polyurethane are closely related to its mechanical properties. According our present knowledge, this study the first time that fiber optic sensing technology has been applied monitor dynamics change in during preparation. effects on expansion force, contractile studied through changing proportion water among ingredients foam. results have shown Bragg grating wavelength varies due power....
Detecting and accurately identifying malignant lung nodules in chest CT scans a timely manner is crucial for effective cancer treatment. This study introduces deep learning model featuring multi-channel attention mechanism, specifically designed the precise diagnosis of nodules. To start, we standardized voxel size images generated three RGB varying scales each nodule, viewed from different angles. Subsequently, applied submodels to extract class-specific characteristics these images....
A field-programmable gate array (FPGA)-based large-capacity sensing network with ultra-weak fiber Bragg gratings (FBGs) is proposed and experimentally studied. The demodulation system constructed to interrogate 1642 serial time-division-multiplexing FBGs a peak reflectivity of about 40 dB equal separations 2.5 m. Two semiconductor optical amplifiers an InGaAs linear sensor controlled by FPGA are introduced the achieve fast, precise, flexible interrogation. low crosstalk spectral distortion...
Pressure sensitivity and gas desorption time are two key parameters that determine the performance of pressure sensors. Polydimethylsiloxane (PDMS) film shows potential in highly sensitive sensor, however trade-off between high low presents a challenge. This article proposes novel sensor with ultra-high ultra-fast based on tapered fiber coated Polydimethylsiloxane/Metal Organic Framework (PDMS/MOF) composite film. By doping specific MOF amino groups into PDMS, adsorption capacity can be...
A distributed optical fiber grating sensing system with large capacity and high spatial resolution is presented. Since highdensity identical weak array was utilized as fiber, the multiplexing number greatly increased, meanwhile, frequency domain reflectometry (OFDR) technology used to implement system. In order eliminate nonlinear effect of tunable light source, a windowed FFT algorithm based on cubic spline interpolation applied. The feasibility experimentally testified, ultimately, can...
Abstract Computed tomography (CT) has been an important complementary indicator in the diagnosis of coronavirus disease 2019 (COVID-19). The pandemic COVID-19 led to a sharp increase number suspected cases, which puts great pressure on radiologists. A computer-supported assisting methodology is essential get preliminary regarding pneumonia infection. In this paper, we proposed deep learning framework for and severity assessment using chest CT. can not only distinguish patients from healthy...
An optical fiber parameter measurement system was constructed based on digital holographic microlayer technology, including an optimized path and a software demodulation system. A single optimal hologram at each angle within 180° view obtained using sample rotation device to extract the phase distribution of sample, which reconstructed optimized, then refractive index inside by laminar analysis algorithm. The experimental results show that reconstruction optimization method used in this...
