提出了基于空间干涉成像的多芯光纤芯间群延时差的测量方法。用CCD记录不同波长下的空间干涉图，利用干涉图中所有像素点的干涉信息构建三维空间干涉光谱，并通过光谱分析可得芯间群延时差。搭建了基于空间干涉成像的多芯光纤芯间群延时差测量实验装置，测量了沟槽辅助型弱耦合七芯光纤芯间群延时差。该方法的测量装置简单，测量精度可达10-4 ps/m，不仅可测量两芯间的延时差还可同时测量任意相邻的多个芯的芯间延时差。测量时使用三维调节台加CCD的组合使得待测纤芯的选择激发更加简单。此外，还研究了多芯光纤芯间延时差的弯曲依赖性，结果显示，随着弯曲半径的增大，多芯光纤芯间群延时差不断减小。

基于空间位移拉曼光谱原理，搭建了一套可以实现微小空间位移的装置，确定了最优的空间位移距离为300 μm，用于穿透皮肤表层，减少皮肤表面水份、油脂等污染物的干扰，最终采集到皮肤内层的水份拉曼信号。该装置采用拉曼波数在3 390 cm-1（水拉曼峰）和2 935 cm-1（蛋白峰）处的强度之比确定组织中的水-蛋白比例，采用便携式光谱仪使设备便于移动，探头和光谱仪以光纤相连使探头可灵活操作，设计满足临床使用要求。实验中检测了7个人、每人10个共70个不同位置的皮肤光谱，将光谱进行去背景算法处理，然后得到精确的拉曼峰强度。以电学法皮肤水份测试仪测试结果作为对比，以组内相关系数作为一致性分析指标，由单个测量组内相关系数为0.889可以看出，基于空间位移拉曼光谱法的人体活体皮肤含水量检测具有较高可行性。
