Fiber Bragg gratings (FBGs) have quickly established themselves as one of the key enabling technologies behind the 'DWDM Revolution'. EDFA gain-equalising professional filters, WDMs and add-drop multiplexers, created as periodic variations in the refractive index of the core of the fiber itself, have all played their part in delivering almost unlimited bandwidth - and in accelerating the transition of the entire telecommunications industry from a digital electronic to a digital photonic world.
FBGs can also be used in the fabrication of optical strain and temperature sensors manufacturers, with quasi-distributed measurements possible using gratings written sequentially into a continuous length of fiber.

The DynoSense 300 is a high scan rate interrogation system for monitoring Fibre Bragg grating sensors. The system is a result of a joint development between XenICs and FOS&S.
The DynoSense 300 can monitor up to 40 FBGs and supports three function modes:
Wavelength mode: in this mode the wavelengths of the different FBGs are recorded as function of time at a scan rate of 3,3 kHz
Spectrum mode: this mode allows to visualize the complete optical spectrum and is for instance of interest for diagnostics of the sensing network
Fast Fourier Transform mode: in this mode the FFT of the recorded wavelength signals is online processed
The system can be controlled with a standard PC via Professional camera Link or Gigabit Ethernet.
Features
- High scan rate: 3.3 kHz
- Broad wavelength window: 1520-1580 nm
- Easy user interface
- Integration time can be software controlled allowing adjustment of measured optical intensity range
