The system contains a broadband light source and performs spectral analysis by means of an Optical Spectral Analyzer (OSA) containing diffractive optics and a linear photodiode array. The OSA can measure the optical spectrum and perform multiple peak detection. The read-out speed can go up to 3.3 kHz and therefore this interrogator is ideal for dynamic measurements like e.g. for vibrational analysis. For this purpose, the user interface calculates online the Fast Fourrier Transform (FFT) of the measured signal.
The DynoSense 300 is a measurement device for monitoring Fibre Bragg Grating sensors at scan rates up to 3.3 kHz. It can monitor a single optical input that can contain multiple FBG-sensors within the wavelength range from 1520 to 1580 nm. The device needs to be controlled externally via a laptop or PC using a USB-interface.
