A true three-dimensional monitor is being developed for the direct display of three- (or higher-) dimensional information. The device is constructed of a three-dimensional array of pixels, actually voxels or volume elements, which in their quiescent state are transparent. When these elements are excited optically through a fiber-optic pigtail, they fluoresce. The sum of many fluorescing elements thus compose a three-dimensional image.
Duncan L. MacFarlane (1994) studied this question.
