APPARATUS AND METHOD FOR IMAGE PROJECTION USING HOLOGRAPHY

摘要

Disclosed are a device and a method to project an image by using holography technology, capable of guaranteeing the quality of an image by preventing wrinkles on a screen by keeping flat the screen with the installation of a screen holder and multiple tension control devices. The device includes: a projector; a reflecting surface reflecting light emitted from the projector; a screen generating an image on the rear side as the light, reflected from the reflecting surface, is projected; a screen holder combined with the screen as an opening part is formed in a side; and a tension control device controlling tension by being connected with the other side of the screen holder. The screen surrounds a support rod in the screen holder through the opening part of the screen holder and then is discharged to be fixed to the screen holder by a support member formed at a tip of the screen.
