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 virtual-image display and virtual camera. Such screen enables to realize virtual-image-based 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 printing, methods for dispersion compensation, and experimental results for the proposed virtual-image display and camera.
Highlights
The fusion of optical images and real objects has been an interesting topic in the field of optics and information technology
Virtual imaging has been used in various applications from head-mounted displays (HMDs) [2] to public theaters [3], where digital images are displayed as overlapping on real objects
We introduced a technology on the holographic Pepper’s ghost based on a virtual-image display and a virtual camera using a holographic mirror and blur-compensation optics
Summary
The fusion of optical images and real objects has been an interesting topic in the field of optics and information technology. In Pepper’s ghost, a virtual image is displayed on real objects by using a slanted half mirror, which can realize surprising visual experiences like optical illusions. The perception of cyber-physical fusion using virtual images mainly relies on the imperceptibility of the frame of the display, which is caused by an axial displacement between the image plane and the screen plane. Such technology has been revisited in the context of augmented reality (AR). More detailed background information for the work described here is given in [21]
