参物光夹角和光强比对全息图拍摄效果的研究

Study on the effect of included angle and intensity ratio between reference beam and object beam on holography

对全息照相实验参考光与物光的夹角和光强比的取值范围进行探讨。拍摄不同夹角和光强比的全息图 ,观察其再现像的效果。实验表明 ,参考光与物光的夹角在 0～ 14 0°、光强比为2∶1～ 12 0∶1的取值范围 ,可得到较满意的结果。

The range of the included angle and intensity ratio between reference beam and object beam in holography have been studied through observation of the reappear images with different included angle and intensity ratio.Experiments show that the results would be satisfactory as the range of included angle is 0～140° and the intensity ratio is 2∶1～120∶1.
