Will enable XR solutions for enhanced safety and convenience and more immersive experiences

Mitsubishi Electric Corporation (TOKYO: 6503) announced today its development of the CielVision aerial display system. The system projects realistic images in mid-air with high brightness and high definition using new digital-optical technology that combines the company’s proprietary aerial-projection optical technology with digital-image processing technology. By significantly improving the visibility of aerial images as well as downsizing the displays, Mitsubishi Electric’s new extended-reality (XR) solution is expected to find applications in a wide range of scenarios.

Aerial displays that provide users with a high sense of presence and immersion are attracting attention due to advances in digital technology. Most aerial displays use a low-cost retro-reflection system that reflect light back in direction it comes from. However, such systems rely on retro-reflective materials and half-mirrors, resulting in dark images due to light loss and low visibility due to reduced resolution. In addition, since these optical systems use constant magnification, a large display screen is required to display a large image, limiting portability.

The new CielVision system uses Mitsubishi Electric’s proprietary aerial-projection optical technology to display clear aerial images with just one free-form mirror. Notably, the mirror’s optical element has a free-form reflecting surface with a complex curvature that allows precise control of reflected light. The system also uses digital-image processing technology to correct any distortion of aerial images. In addition to displaying 2D images, CielVision uses an aerial image superimposition function to display parallax images to both eyes simultaneously, achieving 3D aerial images visible to the naked eye.
