摘要
变线密度光栅在激光核聚变装置、太空探测器上有着广阔的应用前景 ,但是它的检测方法长期以来一直没有发展 ,本文在介绍变线密度光栅的基础上 ,将几何云纹法引入变线密度光栅的检测中 ,从理论上介绍了几何云纹法 ,并就低线密度的变线密度光栅给出了有关理论公式 ,对数据处理方法进行了初步的探讨 。
Varied line space grating (VLSG) is very useful in inertial confinement fusion (ICF) devices. The line density of varied line space grating are introduced. Moire fringe methods are used to measure it. The principle of Moire Fringe is discussed. Some formulae are deduced, and the method of data processing is given.
