A method of recording a scanning hologram with the phase conjugate property of nonlinear crystal is presented.
提出一种用非线性晶体的相位共轭特性记录扫描全息图的方法。

A phasehologram not only has relief modulation but also has refractory index modulation, both modulation will affect the diffraction property of the phasehologram.
位相全息图一般既有浮雕调制又有折射率调制,它们都会对衍射特性产生影响。

A hologram memory with high quality and high information storage density for analog information such as characters, lines and portraits has been made by sampling mesh and random phase shifter method.
