计算全息三维信息获取的研究

Study on the capture of the three-dimensional information in computational holography

计算全息所用的目标数据一般是通过计算机三维软件模拟获得,这样对于计算全息的应用有一定的限制.提出利用三维激光扫描仪获取计算全息图三维数据的方法,研究了计算全息物光分布和扫描三维数据之间的关系,建立了依据三维物体扫描数据的模拟物光波前分布,并分析了立体数据计算全息消隐问题.

Since computing hologram＇s objects data are generally obtained from the computer programming presently, so applications of computing hologram is restricted. A technique to obtain the real object three-dimensional information by laser 3-D scanner in computing holography was proposed. The relationship of the scanner data with the object light distribution for holograms was analyzed, and the object light distribution function was given. Then, a scheme is proposed to remove hiddensurface in computing hologram.
