基于液晶空间光调制器的夫朗禾费衍射实验研究

Experimental Study of Fraunhofer Diffraction Based on Liquid Crystal Spatial Light Modulator

基于液晶空间光调制器对不同形状和尺寸的衍射物进行了夫朗禾费衍射实验研究,实验验证了夫琅禾费衍射规律。实验可以看出相对于传统光刻掩模板衍射物,液晶空间光调制器具有方便、快捷且能及时得出衍射规律的特点。

Based on the liquid crystal spatial light modulator,the Fraunhofer diffraction experiments were carried out on diffracted objects of different shapes and sizes.It can be seen from the experiment that the liquid crystal spatial light modulator is convenient,fast and able to obtain the diffraction law in time compared with the traditional photolithography mask diffraction object.
