| Abstract: | The paper analyzes operating principle of reflective intensity modulated optical fiber pressure sensor. Aimed at the problem of the measurement accuracy apt to be influenced by illuminant fluctuating,photo detector and optical fiber, some measures of fixed amplitude of light source, setting reference channel, modulation and demodulation, self-calibration of zero bit technique are presented. In addition, a series of experiments is made and the system output figure is given. So the stability and accuracy are achieved. |
