ABSTRACT:
A light surface display for providing a three-dimensional image including a plurality of particles suspended within a volumetric display. A first projection system projects sequential slices of electromagnetic energy of one or more wavelengths along the length and width of the volumetric display energizing particles to form a two-dimensional image. A second projection system projects translational slices of electromagnetic energy of one or more wavelengths that intersect with the energized particles across the depth of the volumetric display. A control system synchronizes the projection of the image source and the activation source such that the two-dimensional image and the translational slices energize the particles for a pre-determined length of time so that the particles illuminate to form an illuminated three-dimensional image.
