摘　　要：提出了用多路合成全息语音发音器官图谱显示发音器官动态过程的方法 ,介绍了该全息图的制作过程 ,讨论了制作过程中绘制的二维线条图片的线条宽度与全息图的衍射效率之间的关系。研制的多路合成全息图在白光点光源照射下 ,显现出清晰、明亮的发音器官 (唇、舌、齿和软腭等各部分 )的动态影像。A method making multiplex holograms of speech organs was proposed.Both the line width in the 2D line drawing of speech organs and diffraction efficiency of the multiplex holograms is discussed.A bright 2D line drawing of speech organs is reconstructed from the multiplex holograms when it is illuminated with a small white light source.It is animated that 2D line drawing of speech organs comprises lips,tongue,teeth and soft palate etc when the multiplex holograms is moved slowly.The applied foreground of the multiplex hologram of speech organs is discussed finally.
