APPARAUTS FOR DISPLAYING HOLOGRAPHIC IMAGE

摘要

PURPOSE: A 3D image display apparatus is provided to generate a hologram interference pattern by adjusting electric potential difference applied to a unit cell. CONSTITUTION: A hologram pattern generating unit(1) generates a hologram interference pattern. The hologram pattern generating unit displays a hologram image signal as a 3D stereoscopic image. A control unit(2) controls the electric potential difference which is applied to the hologram pattern generating unit. A reference beam irradiating unit(3) projects a reference beam from the hologram pattern generating unit.
