1. 1. Multiple Fibre Bragg Grating Force Sensor

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Felix Fritzén; [2023]
   Keywords : FBG force sensor; Fiber Bragg Grating force sensing; Fiber optic force sensor; Optical force sensing; Strain-based force sensing; Bragg wavelength shift; Force measurement using FBG; Fiber optic sensing technology; Fiber optic grating sensor;

   Abstract : The purpose of this project is to explore the FBG (Fiber Bragg Grating) technology and create a force sensor. The result can be used as a basis for further projects.The project starts with force and strain measurements. The project then evolves to incorporate multiple FBG sensors. READ MORE

3. 2. DPSK modulation format for optical communication using FBG demodulator

   University essay from Institutionen för teknik och naturvetenskap

   Author : Fredrik Jacobsson; [2004]
   Keywords : Electronics; DPSK; Differential phase shift keying; PSK; FBG; Fiber Bragg Grating; MZI; Mach- Zehnder; optical communication; optical signal; WDM; Wavelength division multiplexing; TU e; Eindhoven; Holland; electro-optical communication; optisk kommunikation; elektrooptisk kommunikation; Elektronik;

   Abstract : The task of the project was to evaluate a differential phase shift keying demodulation technique by replacing a Mach-Zehnder interferometer receiver with an optical filter (Fiber Bragg Grating). Computer simulations were made with single optical transmission, multi channel systems and transmission with combined angle/intensity modulated optical signals. READ MORE
