摘　　要：通过分析各种光栅波长调谐的原理及缺点,提出一种易于实现的高精度光栅波长调谐方法,消除了不确定温度引起的干扰,并推导出公式和使用条件.理论分析和实验结果表明,粘贴于弹片的光栅波长调谐重复性好,易于控制,调谐范围大.Based on the principles of various wavelength tuning techniques for fiber Bragg grating （ FBG）, a higher precision wavelength tuning method is proposed that is easy to realize and by which the interference caused by undetermined temperature is eliminated. The examples of the paramneter design and the experimental procedure, as well as the application conditions are presented. The theoretical analyses and the experimental results have demonstrated that this new method for FBG tuning has the advantages of easy to operate and a wider range of wavelength shift with good repeatability.
