Abstract

A photophoretic display device includes at least one trap light source configured to generate a trap beam, at least one illumination light source configured to generate an illumination beam, a void, and a first reflective surface. The trap beam enters the void and traps a first one or more scattering particles, the trap beam is incident on the first reflective surface at a first incidence angle and is reflected as a first reflected trap beam, the first reflected trap beam traps a second one or more scattering particles, and the illumination beam illuminates the first one or more scattering particles and the second one or more scattering particles that are trapped to generate a volumetric image.
