US Patent 9423682 Ultra high-resolution volumetric three-dimensional display

An ultra high-resolution volumetric three-dimensional (3D) display system comprises an image chamber, and an addressing system to direct a beam of electromagnetic energy at a first wavelength to slice through the image chamber. The beam of electromagnetic energy slices the image chamber along a first axis to provide an image slice. The addressing system comprises a line generator to shape the beam into a line extended along a second axis. An imaging system delivers the electromagnetic energy at a second wavelength to an area within the provided image slice. The line is moved along a third axis to form a three dimensional (3D) image.
