提出了一种多光束数字全息技术来解决当利用菲涅耳数字全息对全息图进行再现时,物体的多个表面无法同时再现得明亮、清晰.该方法是记录时采用多光束照明同一物体的多个表面,增强CCD上接收到的物体侧表面散射光的强度.实验成功地同时再现了物体的多个表面.同时,为了减弱再现像的散斑噪声,采用双线性插值和中值滤波处理图像,获得了质量高的三维物体的再现图像.

The technology of multi-beam digital hologram is proposed to the problem that due to the influence of the illumination,CCD only can receive a little weak scattered wave from the lateral surface of the object,so that it can not reconstruct the multi-surface of the object clearly and brightly at the same time.The proposed method points out that it can use multi-beam to illuminate several surfaces of three-dimensional object.It enhances the intensity of the scattered wave received by CCD from the lateral surface of the object.Multi-surface of three-dimensional object is reconstructed successfully in this experiment.Then,in order to reduce speckle noise of the reconstruction image,is bilinear interpolation and median filter is adopted to process the image,and high quality reconstruction image of three-dimensional object is acquired.
