摘要
采用有良好散射性能的荧光塑料玩具为被拍摄对象,去掉了物光光路中的扩束镜,大大地提高了物光的光强;去掉了参考光中的扩束镜,利用平面镜毛面的漫反射,减弱参考光的光强,使调节物光和参考光光强比在1／2-1／5之间更加方便快捷。实践证明,这种改进提高了全息照相的质量,保证了全息照相实验的顺利进行,使得学生实验成功率大大提高,取得非常好的实验教学效果。
Flubrescent plastic toy which has good scattering character is selected for taking a picture. We could get rid of the beam expander in the object light path, the intensity of the object light was enhanced extremely. We could adjust the intensity ratio between the object light and reference light from 1/2 to 1/5 more rapidly and conveniently .The experiment indicates the improvement enhance the quality oi the holograph and assures that students carry out the holograph experiment successfully. We achieve very good results in the holograph experiment.
