Holographic Pepper’s Ghost: Upright Virtual-Image Screen Realized by Holographic Mirror

Abstract: A holographic mirror is a reflection-type holographic optical element that works as an off-axis mirror. It realizes an upright see-through screen serving as a virtualimage display and virtual camera. Such screen enables to realize virtual-imagebased attractive applications like Pepper's ghost only with a thin optical system. This chapter describes the concept of a holographic-mirror-based virtual-image display and virtual camera, an experimental method for exposing the holographic mirror based on holographic p… Show more

“…HOE can be recorded by the interference of coherent lights, has high flexibility in optical design, and is a thin optical element. In earlier studies, the authors proposed dispersion compensation optical systems using diffractive optical elements (DOE) in single color [13] and in full color [14] . However, these studies were verified in either projection or capturing and had a system complexity problem in full-color systems.…”
