The work in this dissertation is mainly about techniques and applications of PARS (Photoacoustic Raman Spectroscopy) and RIKE (Raman Induced Kerr Effect), and also concerning on techniques of SRGS (Stimulated Raman Gain Spectroscopy) and CARS (Coherent Anti-Stokes Raman Scattering).
论文的主要工作是关于Raman光声光谱(Photoacoustic Raman Spectroscopy,PARS)技术和与Raman共振相关的四波混频——Raman诱导Kerr效应偏振光谱(Raman Induced Kerr Effect,RIKE)技术及其应用所进行的研究;同时也涉及受激Raman增益光谱(Stimulated Raman Gain Spectroscopy,SRGS)和相干反Stokes Raman散射(Coherent Anti-Stokes Raman Scattering,CARS)光谱技术的少量工作。
4) optical low-coherent reflectometry
光学低相干反射计
5) Coherent optical time domain reflectometer
相干光时域反射仪
6) antiphase reflection
反相反射
1.
Through studying it is considered that the observed antiphase reflection is not the reflection from the pile bottom, but is really the reflection of the bedrock surface.
根据桩底反相反射时间计算出的波速往往偏大。
补充资料:相干散射和非相干散射
再辐射的光量子频率和被吸收的光量子频率准确相等的散射过程称为相干散射。在相干散射的情况下,源函数准确地等于平均辐射强度。再辐射的光量子频率和被吸收的光量子频率不相等的散射过程称为非相干散射。在天体物理中,存在一系列因素使散射过程成为非相干散射。主要的因素是:原子的能级有一定的宽度、原子的热运动和湍动以及压力效应等。对于非相干散射,源函数是相当复杂的。
