Abstract
An image output device of the disclosure facilitates enlargement of a stereoscopic image and includes a spatial light modulator, an image irradiation unit, and an address light irradiation unit. The spatial light modulator includes a main surface, a back surface, and pixels, reflects light emitted to the main surface, and modulates a phase of the light for each pixel. The image irradiation unit irradiates the main surface with light including an optical image. The address light irradiation unit irradiates the back surface with address light including a diffraction grating pattern. Each pixel of the spatial light modulator changes a phase modulation amount according to the intensity of the address light from a back surface. The address light irradiation unit dynamically change a diffraction grating pattern's direction on the back surface. The image irradiation unit irradiates the main surface with the optical image corresponding to the diffraction grating pattern's direction.
