Near eye 3D display with concave pin mirror based on bionic compound-eye

Augmented Reality (AR) is a new raising technology, it has great impacts of our future lives. To be well suited for practical use, the device must be small in volume, light in weight, cheap to manufacture and able to project a 3D image with a large field of view (FOV). We demonstrate the near eye 3D display based on the pin-mirror and bionic compound-eye. The bionic compound-eye composed by micro-lens array combined with a micro-display is employed to firstly reconstruct 3D real image, then 3D real image is projected onto the concave pin-mirror, finally reflected and displayed the 3D virtual image into human eye. The whole system is achieved with light weight, cheap cost, comfortable display with a FOV of 88 degrees . In the future this technology could be used for the Metaverse and remote surgeries.
