Abstract
We are researching a holographic display by liquid crystal display(LCD) panels aiming at auto stereoscopic display in the future. When LCD is used as a display device, viewing area and visual field of the hologram are limited from the display area and resolution. To solve this problem, we have proposed a method to expand visual field of the hologram by simultaneous reconstruction. In this method, we calculate hologram with changing the reference light incidence angle on the hologram plane. An image with large visual field is reconstructed with the hologram reproduced by focused spherical wave. Moreover, we constructed the reconstruction optical system by 4K2KLCD whose size is 3.96×1.98cm and converging lens. And the reconstruction experiment of holograms by focused spherical wave showed that the proposed method was effective.
