We demonstrate a multichannel high-speed fiber Bragg grating (FBG) interrogation system utilizing a field programmable gate array (FPGA). A temperature-controlled Fourier domain mode locking laser was operated with a sweep rate of 50.7kHz, sweep bands of 35nm, and an output power of 0.91mW. This laser enabled an FBG measurement speed of up to 9.9 <italic/>s. Real-time processing could be achieved...
