In this paper we have derived the expression of diffraction angle, the frequency shifting effect and the efficiency of diffraction for the parallel-combined sinusoidal phase grating based on mechanical moving by using Huygens-Fersnel principle.
用Huygens-Fresnel原理,对平行组合的正弦位相光栅的机械移动的衍射效应,导出了衍射角度、移频效应及衍射强度的表达式,并将结果和两种典型位相光栅的移动效应进行了比较,结果表明:这种组合式位相光栅机械移动时的衍射效应的特点,预期有一定的实际应用。
补充资料:牙齿
又称“牙”。具有一定形态的高度钙化的组织,有咀嚼、帮助发音和保持面部外形的功能。在人体,一生中先后长两次牙,首次长出的称“乳牙”,到二岁左右出齐,共二十个。六岁左右,乳牙逐渐脱落,长出“恒牙”,共三十二个。按形态可分为切牙、尖牙和磨牙。切牙的功能是切断食物,双尖牙用以捣碎食物,磨牙则能磨碎食物。
