为了更方便地编写基于串口通信的光纤光栅传感网络的分析软件,实现对光纤光栅传感网络的远程控制,设计了一种VB语言环境下编写光纤光栅传感网络的分析软件的方法。利用VB语言环境实现了PC机和单片机之间串口通信、PC机对单片机的控制、数据处理以及图形绘制功能。并利用已标定的光纤光栅对可调谐激光器解调法的光纤光栅传感网络及其解调软件的精确性和实用性进行测定。实验结果表明该软件具有设计简单、工作稳定的特点。本文也为光纤光栅传感网络的远程控制和联网控制提出了思路。 相似文献

In-situ growth of Ca/P salt on Ti surface induced by femtosecond lasers in hydroxyapatite suspension 下载免费PDF全文
Pure Ti plate surfaces are micro-ablated by femtosecond lasers in the ambience of hydroxyapatite suspension. It is found that three-stage hierarchical surface structures are produced with various laser energies. When the laser energy is 150 μJ, a lava-like structure with a distribution of nanoholes is dispersed evenly on the laser ablated surface. While in the case of 300 μJ, the grooves-and-islands micro-patterns covered with nanoparticles are generated on the surface. Remarkably, Ca/P based substances are revealed to firmly deposit on the micro-structured surfaces. More phosphate growth is seen for the higher laser energy. Discussions suggest that the additional elements deposition could be attributed to the chemical reaction of plasma related ions in the suspension and their subsequent crystallisation on the fresh surfaces of Ti plate due to the femtosecond laser ablation. 相似文献
