Title:
光変調用マイクロミラーを用いたホログラフィ投影システム
Document Type and Number:
Japanese Patent JP5427034
Kind Code:
B2
Abstract:
The invention relates to a holographic projection system wherein light modulator means SLM with electromechanically moved micro-mirrors modulate a light wave front LWmod. According to the invention, a hologram processor HP sets micro-mirror surfaces of prior art spatial light modulator which are disposed as controllable diffraction gratings on a substrate of a control circuit, such that they reach a certain diffraction grating amplitude, by moving them continuously at right angles to the substrate, said diffraction grating amplitude being dependent on the content of a sequence of video holograms. The diffraction grating modulate a light wave which is emitted by the light modulator means and which generates illumination capable of generating interference according to a phase hologram, so that the modulated light wave is used directly for the holographic reconstruction.
