| Abstract: | A new scheme is developed in which the phase modulated signal generator is designed for optical fiber sensor, based on the single_chip computer and quasi_DMA technique,to resolve the problems of interference optical fiber sensor with which the signal is difficult to generate and control.The comparison of results from experiments and computer simulation show that the two kinds of wave froms are very similar,indicating the feasibility and superiority of this method. |
