摘　　要：LabVIEW是一个高效的图形化程序设计环境,它在测量、测试及工业控制领域已有广泛的应用。介绍了一种基于 LabVIEW的光纤光栅波长移位检测系统,依靠虚拟仪器工作平台(LabVIEW),实现了PC机与可调谐激光器之间的通信及数据采集、分析和显示;从而快速、智能化地实现了光纤光栅波长移位检测。实验表明该系统的波长检测灵敏度为0．00965 nm/℃,波长分辨率为2pm,波长检测范围不受系统限制,一般可达30 nm以上。LabVIEW is a high efficiency graphical platform with extensive applications in measuing, testing and industrial control realm. A demodulator system based on LabVIEW is described. Communication between PC and tunable laser, data acquisition, data analysis and display are implemented, and the wavelength-shift detection is achieved rapidly and intellectualized with LabVIEW. The wavelength detection sensitivity of the system is demonstrated to be 0.00965 nm/℃ ,and the wavelength resolution is better than 2.0 pm.
