Volumetric displays

Definition

Volumetric displays are three-dimensional visual technologies that present images in a way that allows viewers to perceive depth and spatial relationships without the need for special glasses. These displays create volumetric images by illuminating points in space, often using methods like rotating screens or laser projections, enabling users to interact with visual content from multiple angles. This immersive quality makes volumetric displays especially relevant in fields like virtual reality, medical imaging, and simulation training.
