Mirage Hyperchromatica (MiH) presented a poster at the SPIE VR AR MR 2022 conference in San Francisco. This work was a result of collaboration between MiH and Fraunhofer Institute for Applied Optics and Precision Engineering (IOF). The poster attracted a lot of attention.

Abstract: We present a new hyperchromatic laser-based multifocal display. In the proposed design multiple full-colour virtual image planes can be displayed simultaneously at different depths in front of the observer through wavelength (de-)multiplexing. Each depth plane is displayed through its own combination of red, green and blue lasers at specific wavelengths. Hyperchromatic displays can be useful for augmented (AR) and mixed reality (MR) applications where real and virtual objects are located at different depths in front of the observer because they allow the human eye to focus on virtual objects and reduce the vergence-accommodation conflict (VAC). We present a laboratory demonstrator where the images generated by two red lasers (630 nm and 960 nm) were separated by more than 3 meters. We also discuss the applicability of the technology to the automotive head-up-display (HUD) systems and present an HUD system based on low-cost off-the-shelf components.
