| Abstract: | The theory foundation of pressure detection in PCF pressure sensor is deduced in this article, the PCF pressure sensor system structure is designed, the source performance requirements are proposed in PCF pressure sensor, the semiconductor laser is choosed as the sensor system source. A whole control design of the LD work stability is put forward,the LD noise control module, and power control module and temperature control module and wavelength control system are gived by circuit analysis methods. the LD operation stability can be effectively protected by noise, power and temperature control in LD,it is a widely prospect that energy supply by using semiconductor lasers in PCF pressure sensor in the future environmental monitoring and pressure field applications. |
