We propose a virtual camera that can pass through a small hole in an obstruction to capture an image on the other side. Recently, free-viewpoint television technology has enabled the generation of video in which viewpoint images are captured from locations where cameras are not actually placed. However, capturing the images of objects concealed behind obstructions or beyond a camera’s field of view is a challenge. We designed an optical transformation system that utilizes a conventional camera… 
Aerial Imaging by Retro-Reflection for Mid-Air Image Display and Camera Viewpoint Transfer
TLDR
The proposed optical system uses aerial imaging by retro-reflection (AIRR) instead of MMAPs for mid-air image display and camera viewpoint transfer and the results indicate that AIRR achieved a wider imaging range than MM APs forMid-air telepresence systems.
An Optical Design for Avatar-User Co-axial Viewpoint Telepresence
TLDR
A system that takes the avatar from VR space to real space with the help of mid-air imaging technology and an application called Levitar, which uses a dual camera to output the captured video to the HMD and controls the camera gaze direction.
Suppression of floating image degradation using a mechanical vibration of a dihedral corner reflector array.
TLDR
A method of suppressing degradations which appear as high-frequency noise by using mechanical vibration is proposed, which was confirmed through an analysis of the floating image quality in the frequency domain.
