摘要
本文提出一种制作等间距同心环形全息光栅的方法。理论分析表明,单色平行光通过圆锥形透镜后,在一定区域内波场的等强度点分布是一组间距相等的同心圆环。将全息底片置于此波场中曝光,即得到等间距环形全息光栅。实验结果表明,这种方法切实可行,效果令人满意。
The article provides a method of making an equal-distant ring hologram grating. A theoretioal analysis shows that the fringes formed are a series of equal-distant, concentric circles in a certain range, when monochromatic parallel beams is passed through a conic lens. When a hologram film is located at the field, the grating will be obtained. The experimental result shows that the method is practicable and satisfactory.
