Patent number: 11914145Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.Type: GrantFiled: December 10, 2020Date of Patent: February 27, 2024Assignee: KWANGWOON UNIVERSITY INDUSTRY-ACADEMIC COLLABORATION FOUNDATIONInventors: Seung Hyun Lee, Lee Hwan Hwang, Jae Hyun Lee, Sung Jae Ha, Soon Chul Kwon, Kwang Pyo Hong
