This study presents a novel reflective fiber Fabry–Perot (F–P) salinity sensor. The sensor employs femtosecond laser to fabricate an open liquid cavity, facilitating the unobstructed ingress and egress of liquid, thereby enabling direct involvement in light transmission. Variations refractive index induce corresponding changes effective optical path, which subsequently influences output spectrum. dimensions quality are meticulously regulated through combination cutting chemical polishing,...
Fiber Bragg gratings (FBGs) have become a promising sensor element for measuring temperature, strain and other parameters. However, there exists cross-sensitivity between temperature strain. An all-fiber sensing system composed of gold-plated FBGs acrylic has been proposed fabricated, which can achieve simultaneous measurement axial temperature. Using spectrometer to monitor the shift in transmission spectrum real time, ambient applied be measured conveniently. The experimental results show...
Abstract The fiber Bragg grating vibration sensor has received a lot of attention due to its unique performance. However, the natural frequency limits development and application. This paper presents an acceleration with isosceles triangular cantilever mass block structure, which high sensitivity. optical sensing system consists two gratings. One section is pasted on serves as accelerometer; other used reference grating. first-order accelerometer 8356 Hz, sensitivity 0.46 pm g −1 . A test...
Objective This study was performed to evaluate the position and morphology of temporomandibular joint in female patients with skeletal class II malocclusion investigate association between disorders facial types using cone-beam computed tomography. Methods A lateral cephalogram taken determine each participant. Sixty aged 16 28 years were divided into high-angle, low-angle, control groups. The shape condyle–fossa measured assessed on tomography images 120 joints. Results Some condylar...
Fiber Bragg grating (FBG) acceleration sensor is an important branch of FBG application and has irreplaceable advantages compared with electronic accelerometer. An high sensitivity natural frequency designed. This adopts a double cantilever structure to sense the vibration perpendicular axis. Compared single structure, increased without reducing sensing length. Through above design material selection, shows 8658 Hz its 0.44 pm/g. After photoelectric demodulation used, 52 mV/g linearity...
This paper presents a novel method of measuring spatial rotation angle with dual-axis micro-electro-mechanical systems tilt sensor. When the sensor is randomly mounted on surface rotating object, there are three unpredictable and unknown mounting position parameters: α, sensor's swing plane; β, between axis horizontal γ, plane axis. Thus, model established to describe relationship axis, plane, corresponding analytical equations derived. Furthermore, eliminate deviation caused by uncertain...
The phase noise in phase-sensitive optical time domain reflectometer (φ-OTDR) system is primarily composed of laser frequency drift, beat noise, electrical and fading which affect demodulation vibration signal analysis. In order to enhance the signal-to-noise ratio (SNR), a suppression method based on Successive Variational Mode Decomposition (SVMD) Pearson Correlation Coefficient (PCC) studied introduced. SVMD-PCC initially decomposes adaptively into several intrinsic mode functions (IMFs)...
Abstract Microorganism plays a vital role in the decomposition of vertebrate remains nature nutrient cycling, where postmortem microbial succession patterns during remain unclear. Here, hierarchical clustering based on Manhattan distances analyzed similarity and difference among intestine from 16S rDNA sequences mouse model. Based similarity, seven different classes are obtained. Generally, normal intestinal flora cecum gradually decreases with changes living conditions after death, while...
