Paper Abstract

A fast spectrometer based FBG interrogator will be discussed. This unit is constructed around a fast linear InGaAs array with 1024 pixels and capable of reading out 40000 lines per second. This array is integrated in a double reflective grating spectrometer, dispersing the spectra in the [1510 - 1590 nm] band. The signal treatment electronics is capable of determining the peak wavelength position of at least 8 birefringent FBG sensors or 16 single FBG sensors at the data rate, supplied by the image sensor.
