The technology of output signal photoelectric conversion in Photonic Crystal Fiber pressure sensor

摘要：

Photoelectric detector is the interface devices between the optical and electronic systems in the photoelectric information conversion system. The basic sensitive principle is analyzed in photonic crystal fiber pressure sensors, and the photonic crystal fiber pressure sensor systems and detection system based on strength decoding are designed, beside considering the sensor output signal current value is small, so the InGaAs / InP-APD photodetectors which is in accordance with the performance parameter of photodetector are chosen as the basic devices in the photoelectric conversion. The output signals are amplified by use of pre-signal amplification circuit and dual op amp differential input amplifier circuit. The output signals are detected and the changes of the external pressure are rapidly monitored by the designed detectors and the amplifier circuit.
