激光诱导击穿光谱已用于测量大气条件下粉煤无烟煤中的有机氧含量。 提出了特殊的光谱处理方法，包括通过与N（I）线比较光谱相关系数，选择与O（I）线的光谱相关系数，与N（I）线进行内部归一化以及温度校正来选择最佳的O（I）发射线，以满足多光谱分析线分析方法，可得出最准确的定量结果。 提出了确定煤中有机氧含量的标定方法，通过对六个无烟煤样品进行的实验评估，其准确度为1.15-1.37％，平均相对误差为19.39％。 还研究了相对测量误差分布。

A new method for increasing laser induced damage threshold (LIDT) of dielectric antireflection (AR) coating is proposed. Compared with AR film stack of H2.5L (H:HfO2, L:SiO2 on BK7 substrate, SiO2 interfacial layer with four quarter wavelength optical thickness (QWOT) is deposited on the substrate b

We propose a method for simultaneous 3D temperature and velocity measurement of a micro-flow field. The 3D temperature field is characterized with two-color laser-induced fluorescence particles which are tracked with micro-digital holographic particle tracking velocimetry. A diffraction-based model
