    Abstract: A complex spatial light modulator includes a polarization-phase modulator for separating an incident beam into a first beam having a first polarization and a first phase, and a second beam having a second polarization and a second phase, and for outputting the first beam and the second beam; and a beam synthesizer including a prism structure formed of an optical anisotropic material having a first refractive index with respect to the first beam having the first polarization and having a second refractive index, different form the first refractive index, with respect to the second beam having the second polarization, where the beam synthesizer combines the first beam and the second beam.

    Abstract: An illumination unit is provided including a coherent light source; a projection optical element which focuses a light beam emitted from the coherent light source onto a focal plane; and a holographic optical element interposed between the coherent light source and the projection optical element, and having an interference pattern formed thereon. The holographic optical element diffracts the light beam emitted from the coherent light source and emits the diffracted light to the projection optical element. Here, the interference pattern on the holographic optical element may have information that diffracts the light beam and thereby cancels a diffraction of the light beam due to an aberration of the projection optical element.
