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。

In this paper I have shown that the double phase-only matched filtering can be realized by a computer generated hologram of detour phase with phase coding for two objects.
