分子振动谱广泛应用于化合物分子结构的测定、未知物的鉴定以及混合物成分的分析，是传感识别物质性质和特征的重要指纹。提出了基于石墨烯带阵列的分子振动谱传感模型，并采用数值仿真方法对模型进行了验证。结果表明，通过调节石墨烯带的化学势、阵列周期以及占空比，可以灵活地调控石墨烯带阵列的透射带宽；通过在检测区填充物质，发现透射谱的形状与被检测物的分子吸收谱一致，表明该传感器能够识别物质分子的振动指纹；透射谱的形状对检测区域填充物质的厚度不敏感，传感器的稳健性好。

Since the first edition there have been many changes in the equipment available for measurements and the growing interest in Transmission Error measurement has spawned numerous approaches that are not always clearly described. Each author has a tendency to extoll the virtues of his approach but rarely points out the corresponding disadvantages, so I have attempted to compare systems. A range of new problems in from industry has generated some interesting additional topics. I have also added discussion of some of the less common but puzzling topics such as high contact ratio gears which are increasingly being used to reduce noise. Testing procedures are also discussed in more detail together with some practical problems and some slightly extended description of the failures that may be encountered and their relationship, or lack of it, to noise problems. I hope that few errors or mistakes have crept into the book but if readers discover errors I will be very grateful if they let me know (e-mail jds 1002@eng.cam.ac.uk)

本文提出一个新的光学双稳性模型.基于平均场近似,慢变振幅近似和绝热近似的思想,把光学双稳系统看成一个“黑箱”,类比非线性振动理论,指出不同的光学双稳过程(包括不同的工作物质和不同的腔(F-P腔或环腔)),能用一个恰当的强迫振动方程统一地描述.方程中所包含的都是可测量的宏观参量,使得可能直接用实验拟合,与理论结果进行定量对照.用振动理论的方法,把方程演变成自治方程组,从而方便地得到光学双稳性稳态和动态解的一般形式.并用若干已报道的具体例子验证了这个模型的普适性.

提出了一种基于多模干涉效应(MMI)的单模-多模-间隙-单模（SMGS）光纤悬臂梁振动传感器。采用光束传播法（BPM）对这种结构的光传输性能进行数值模拟，并通过有限元分析方法对光纤悬臂梁进行了振动模态分析，从理论上优化设计了该类光纤振动传感结构。在实验上制备了长度为22 mm的悬臂梁结构，详细研究了多模区光纤的长度对声频振动响应的影响。实验结果表明，该SMGS振动传感器在130 Hz时响应效果最好，对应的声压灵敏度为4 mV/mPa，线性相关系数为0.9962，线性度和可重复性良好，并且实验结果和理论模拟结果相符合。这种光纤振动传感器具有制备工艺简单、成本较低和灵敏度高等特点，有望应用于对某些具有特殊振动频率点的远距离振动传感。
