摘要
同时利用两个振源,在液体表面上产生两列低频表面波,实现了多振源条件下表面声光效应,观察到清晰、稳定、反衬度高的声光衍射条纹.当引起两列表面波的两个振源频率具有倍数关系时,声光衍射条纹的极大值位置与较小频率的振源单独存在时所产生表面波的极大值位置相同,与较大频率的振源单独存在时所产生表面波的极大值位置部分相同.当引起两列表面波的两个振源频率不具备倍数关系时,不仅观察到单振源的衍射条纹,而且也观察到了双振源的干涉条纹.理论上得到多振源衍射光场和表面波波长、振幅之间的解析表达式,理论规律与实验结果吻合较好.
Abstract
In order to achieve the multi-vibration source surface acousto-optical effect,two vibration sources were used to generate two low-frequency surface wave on the liquid surface at the same time,and also the clear,stable,high contrast acousto-optic diffraction fringes were observed.When the two surface waves′ frequency with multiple relations,the spot positions of diffraction pattern are same as the smaller frequency alone and are part of same the larger frequency alone.The diffraction fringes of single vibration source,and the interference fringes of double vibration source were observed when they don′t have multiple relations.It was derived that the analytical expressions between multi source diffraction field and the wavelength of surface waves or and amplitude.The theoretical analysis agree well with experimental results.
