Holographic three dimensional images of objects can be displayed via a
device comprising micro holographic optical elements (MHOEs). A device
for displaying holographic three dimensional images of objects can
comprise a laser source, a spatial filter using a micro holographic
optical element (MHOE) lens, a collimating MHOE lens, a spatial light
modulator, and cylindrical MHOE lenses. A holographic three dimensional
image of an object can be displayed using MHOEs by emitting a coherent
light, filtering and expanding the light, aligning the expanded light,
modulating the aligned expanded light, and focusing the modulated light.
