We present in details the development of a 360° volumetric display based on the use of a transparent projection surface. The optical scheme derives from the Pepper’s ghost configuration, known as holographic display. Our optical system requires high angular diffusion efficiency and an innovative transparent retro-reflective surface has been developed for that purpose. This surface is made of sparse cube corner distribution and we give some elements of its design and characterization. We describe also the optical design of the 360° display and gave the feedback of its presentation to the public during a symposium.
