PROBLEM TO BE SOLVED: To electronically obtain a color hologram by a simple configuration without using a color imaging device.;SOLUTION: An ICH-CH optical conversion part includes a phase conjugate mirror 104 and reflecting mirrors 122 and 124. RGB coherent light W3_CH emitted from a reference wave light source 154 is split into two by a beam splitter 136, and one RGB coherent light W32_CH is made incident on the phase conjugate mirror 104 from the same direction as incoherent light W2_ICH being object light, on the same axis as the incoherent light. RGB coherent light W5_CH which is emitted from an object wave light source 152 and is modulated with frequencies different by RGB is made incident on the phase conjugate mirror 104 to generate coherent phase conjugate object light W7 modulated by RGB. RGB coherent light W31_CH is used as reference light and has a polarization direction equalized to that of the phase conjugate object light W7, so that they are coaxial, and then the reference light and the phase conjugate object light are made incident on a scan type imaging part 5 for monochrome and interference fringes are formed on an imaging surface by causing the reference light and the object light to interfere with each other.;COPYRIGHT: (C)2011,JPO&INPIT
