Abstract

Holography is well-known technique of 3-dimensional imaging. A medium recorded the image is called hologram. To reconstruct objects, the holograms are illuminated with light waves. When fluorescent tubes or light emitting diode (LED) arrays illuminate holograms, reconstructed images are blurred, since a position of reconstructed image depend on illumination angle and angular-spreading light waves emitting from these plane light-sources reconstruct a series of the holographic images. Here we propose a blur suppression method of the holographic images by limiting incident-angle spreading of light waves by using surface plasmon polaritons (SPP) [1].
