CSpace Prototype for 3D Image Display

By DE Editors

3DIcon (Tulsa, OK) says CSpace is a true volumetric 3D display technology that enables an image to be viewed without any special viewing aids. The image has actual volume, i.e., does not use cues to create the illusion of 3D like most 3D-on-2D systems. It preserves the spatial relationships that exist in a true 3D scenario.

The images can be viewed from virtually all sides and angles, i.e., is an image viewable from 360 degrees.

The prototype uses off-the-shelf lenses that have been assembled in the lab. Also, Display images by using more voxel data. Through improved computing, we will be displaying images using several times more data. This will enable the display of images with significantly higher detail. We expect to complete this in the coming weeks.

CSpace creates a virtual moving screen display that contains a variety of particles suspended within its volumetric image space. When these particles are excited by two different infrared lasers, they illuminate to generate a 3D image. These particles include up-conversion materials that convert lower energy beams into higher energy visible beams and function as light emitting phosphors.

CSpace includes a first projection system, such as a Digital Light Processing (DLP) spatial modulator, projecting wavelengths forming sequential slices of a two-dimensional image along the length and width of the volumetric display. A second projection system, again a DLP spatial light modulator, projects different wavelengths forming translational slices having any predetermined screen shape across the depth of the volumetric display.
