Air Volumetric Display HoloDesk Released: 3D Images Float in Air Without Glasses or Headsets
HoloDesk uses laser-excited nitrogen molecules in the air to produce microplasma light points, constructing 360-degree-viewable 3D images in a 30-centimeter space above the desk.
Air Volumetric Display HoloDesk Released
On September 16, 2030, Israeli startup Looking Glass Labs released the HoloDesk air volumetric display. The device uses focused lasers to excite nitrogen molecules in the air, producing microplasma light points, presenting 3D images in approximately 30 centimeters of space above a desk without any screen, glasses, or headset.
HoloDesk works by using three high-pulse-frequency ultraviolet lasers (wavelength 266 nanometers) to create microplasma at their intersection points in the air. Each light point is approximately 100 micrometers in diameter and lasts about 1 nanosecond. Through high-speed scanning, the system can produce approximately 200,000 light points per second, forming a 3D image perceptible to the human eye.
Looking Glass Labs CEO Eran Ben-Artzi said HoloDesk's display volume is 30x30x30 centimeters, with a resolution of approximately 100 million voxels and a frame rate of 30 fps. "You can see a rotating globe, a beating heart model, or a set of architectural drawings floating above your desk, appearing as complete 3D structures from any viewing angle."
HoloDesk is currently priced at $12,000 per unit, primarily targeting professional users in architectural design, medical education, and industrial design. The company plans to reduce the price to below $3,000 by 2031 to enter the consumer market.
It should be noted that HoloDesk's microplasma produces a faint crackling sound (approximately 40 decibels) and currently can only display monochrome (cyan-white) images. Ben-Artzi said a color version is under development and is expected to arrive by 2032.
