Abstract

Dihedral corner reflector arrays (DCRAs) are imaging devices that form real images and are used in a variety of applications, including floating virtual touchscreens and image presentation around physical objects. However, they induce several types of degradations to floating images. It is desirable to suppress these degradations to provide better viewing experiences. This paper proposes a method of suppressing degradations which appear as high-frequency noise by using mechanical vibration. The effects of vibrating the DCRA were confirmed through an analysis of the floating image quality in the frequency domain.
