Abstract
A spatial projection apparatus is provided. The apparatus includes an optical medium that diffuses a projected light. The apparatus further includes a light guide optical system that guides the projected light diffused by the optical medium and forms an image on a spatial imaging unit. The optical medium can be formed with a plate shape, a film shape, a three-dimensional shape including unevenness, in smoke-form, fluid-form, or mist-form.
Claims8
A spatial projection apparatus comprising:
- an optical medium that diffuses a projected light;
- and
- a light guide optical system that guides the projected light diffused by the optical medium and forms an image on a spatial imaging unit,
- wherein
- the optical medium diffuses the projected light formed into an image on the optical medium, and
- the light guide optical system reimages the projected light diffused by the optical medium on the spatial imaging unit.
