Control and Tanning of CCD Processor Using FPGA

The most straightforward means for interrogation of a FBG sensor element is to illuminate the FBG sensor(s) by broadband source & the narrowband component reflected by the FBG is directed to the wavelength detection system. CCD is illuminated by the optical signals reflected by the FBGs. Each FBG reflects a distinct wavelength. All the optical signals fall on a diffraction grating which is placed before the CCD. The diffraction grating disperses each wavelength in a different direction (i.e. on different pixels) on to the CCD. Then complete arrangements like source, FBG, detection unit etc. required for a FBG based sensor system.
