Image photography method, image photography play method, spatial lighting modulator, image play device, and digital hologram forming device

摘要

An image photography play method which is suited to playing a stereoscopic video. The image photography method includes: a step of forming a hologram pattern from a reference light and a subject light; a step of digitally processing the obtained hologram pattern; a step of writing the digitized hologram pattern as a magnetized vector pattern to a spatial lighting modulator which is formed from a magneto-optical material; and a step of inputting linearly polarized light into the spatial lighting modulator and playing an image according to the digitized hologram pattern.
