In recent years, Rain Technology has made significant strides in the development of its Anamorphic-XR optical engine designed for augmented reality (AR) and virtual reality (VR) headsets. Dr. Michael Robinson, the company’s chief scientist, will be sharing these advancements at Display Week 2024.
The Anamorphic-XR technology is aimed at improving the performance of AR and VR headsets by delivering high-definition, wide-angle images in a compact and transparent design. The technology combines an anamorphic microdisplay with an anamorphic waveguide fitted with a cylindrical mirror to reflect light upwards, allowing users to see both real-world and virtual images in their field of vision.
One of the key benefits of Anamorphic-XR is its ability to increase image magnification independently in different planes to enhance resolution and field-of-view. By utilizing polarization instead of diffraction to extract light from the waveguide, the technology produces a brighter and sharper image that overcomes common challenges faced by AR/VR devices such as size, eye relief, field-of-view, resolution, and brightness.
According to Rain Technology, their research and development have demonstrated that incorporating a mirror for the lateral optical path and lenses for the transverse path can significantly enhance the field-of-view and efficiency compared to traditional AR/VR optics. This can help overcome optical hurdles such as wide-field image fidelity, brightness, dynamic range, and eye strain.
After his presentation at Display Week 2024, Dr. Robinson will be publishing a technical paper titled “Anamorphic-XR: Imaging Waveguide Technology for Efficient and Wide Field-of-View Near-Eye Display.” This paper will provide valuable insights into how this cutting edge technology works and its potential applications in AR/VR headsets.
