Holographic imaging

摘要

Technologies are generally described for generating an image in a holographic imaging device by causing multiple reflections of a hologram reconstruction light on one side of a display panel in the holographic imaging device. An example device may include a display panel, a semi-transparent mirror layer on the display panel, a mirror layer at a side of the semi-transparent mirror layer opposite to the display panel, and a light irradiation unit opposite to the semi-transparent mirror layer. The light irradiation unit may irradiate a hologram reconstruction light on the semi-transparent mirror layer at a predetermined incident angle. The semi-transparent mirror layer may reflect a portion of the hologram reconstruction light such that the reflected portion of the hologram reconstruction light may be incident on the mirror layer. The semi-transparent mirror layer may transmit the other portion of the hologram reconstruction light to cause interference in the hologram.

1. A holographic imaging device, comprising:
a display panel configured to display a hologram; a semi-transparent mirror layer disposed on the display panel; a mirror layer disposed at a side of the semi-transparent mirror layer opposite to the display panel; and a light irradiation unit configured to irradiate a hologram reconstruction light to be incident on the side of the semi-transparent mirror layer opposite to the display panel at a specific incident angle, wherein the semi-transparent mirror layer is configured to reflect a portion of the hologram reconstruction light such that the reflected portion of the hologram reconstruction light is incident on the mirror layer, and the semi-transparent mirror layer is configured to transmit another portion of the hologram reconstruction light effective to cause interference in the hologram displayed by the display panel.
