  • 提出了一种制作高频线性可变频率光栅的新方法,并给出了光栅空间频率的表达式.通过在相干的两光路中插入特殊透镜,可以实现线性可变空间频率光栅的制作,而且通过适当地调节实验参数可以改变空间频率的变化率.给出了相应的模拟全息图.

     

    In this article, a new method to produce gratings with linearly variable spatial frequency is proposed and the expression of grating frequency is obtained. By inserting special lenses into the two light paths, the production of grating with linearly variable spatial frequency is realized. The modification of frequency can be easily achieved by properly adjusting the experimental parameters. The simulated hologram is given.
