摘要
通过数字全息实验平台,制作平面全息光栅,利用高精度CMOS相机记录两束平行光的干涉,改变两平行光束的夹角和光斑相对方向,观测干涉条纹的疏密变化和方向变化,加深学生对光的干涉的理解,训练学生基本光路的搭建与调整。
HoLographic gratings were made through digital holographic experiment, in which two parallel light beams interference was recorded by a high precise CMOS camera.The angle of the two parallel light beams was changed, and so was the relative position of the light spots.So the grating constant and the direction of the inter- ference of two parallel beams could be researched.By this experiment students could understand the light inter- ference deeper, and train their basic skills for optical experiment.
