Code Division Multiplexing Applied to FBG Sensing Networks: FBG Sensors Designed as Discrete Prolate Spheroidal Sequences (DPSS-FBG Sensors)

Arbitrary Strain and Temperature Distribution Sensing Using Two FBG Pairs

We use two pairs of FBGs to perform simultaneous strain and temperature field measurements. The first pair of FBGs, comprising one uniform FBG and one chirped FBG, measures the strain and temperature fields, while the second pair of FBGs, also comprising one uniform FBG and one chirped FBG, measures the temperature field only. A genetic algorithm is applied to reconstruct the arbitrary strain a...

Self-Protected Sensor System Utilizing Fiber Bragg Grating (FBG)-Based Sensors

Influence of Individual Differences on the Calculation Method for FBG-Type Blood Pressure Sensors

In this paper, we propose a blood pressure calculation and associated measurement method that by using a fiber Bragg grating (FBG) sensor. There are several points at which the pulse can be measured on the surface of the human body, and when a FBG sensor located at any of these points, the pulse wave signal can be measured. The measured waveform is similar to the acceleration pulse wave. The pu...

Deformation Sensing of Colonoscope on FBG Sensor Net

Owing to the complex condition and non-visualization of human intestinal, Loop formation of colonoscope often happens to hurt the patient during the diagnosis of colon. This paper presents a deformation sensing method using Fiber Brag Grating(FBG) sensor net to real-time display the shape of colonoscope that would help the endoscopist how to manipulate the colonoscope into the body and reduce t...

Compressive Sensing of Analog Signals Using Discrete Prolate Spheroidal Sequences

Compressive sensing (CS) has recently emerged as a framework for efficiently capturing signals that are sparse or compressible in an appropriate basis. While often motivated as an alternative to Nyquist-rate sampling, there remains a gap between the discrete, finite-dimensional CS framework and the problem of acquiring a continuous-time signal. In this paper, we attempt to bridge this gap by ex...
