Abstract
A holographic three-dimensional (3D) image generating apparatus that may use a collimated directional backlight unit (CD BLU) is provided. The CD BLU may output a collimated light of which an emitting light is adjusted. The convergent lens may enable the outputted collimated light to converge into a viewing area of a viewer and thus, a viewing window may be generated. A spatial light modulator (SLM) may perform spatially-varying modulation with respect to the collimated light converging into the viewing area to generate a focused beam.
