Problems solved by technology

[0004] However, the existing imaging device uses the image information presented by the reflective lens, the reflective panel or the optical light guide component to form the image in the pupil, and this kind of imaging device cannot see through the external environment during use, thus restricting its use conditions, and some manufacturers use Spectroscopic components or optical light guide components enable the overall system to be able to see through the external environment, but waste excess photon energy in the imaging process, resulting in low photon utilization rate of the image, so it is necessary to develop the ability to see through the surrounding environment and improve Imaging device for photon utilization

Abstract

A one-dimensional scanning type pupil projected display device comprises an image scanning part and a key optical component. The image scanning part comprises a system light source, a developing machine, a mechanical type one-dimensional scanner, a spectroscope and a lens group. The system light source evenly projects received image information through a light-even piece, and the image information is deflected through the spectroscope to the developing machine which receives the image information to generate a picture. The developing machine projects the picture to the one-dimensional scanner through the lens group. The one-dimensional scanner reflects the picture to the key optical component which diffracts the received picture to a pupil of a user for imaging. According to the system light source, a plurality of light-emitting diodes with different wave lengths are mixed and matched to project white light. The light-even piece is a light guide pipe or a diffusing piece or a combination of the light guide pipe and the diffusing piece. According to the one-dimensional scanning type pupil projected display device, the one-dimensional scanner is matched with the key optical component, and compared with an existing imaging device, visual penetrability and high photon using rate are achieved.

Description

technical field [0001] The invention relates to a one-dimensional scanning pupil projection display device, in particular to a one-dimensional scanning pupil projection display device which can see through the surrounding environment and has high photon utilization rate. Background technique [0002] With the development of science and technology, modern people gradually pay more attention to their own leisure and entertainment, and pay more and more attention to the shock and feeling that images can bring, regardless of the comfort, presence, convenience and privacy when watching. In addition, many people pass the time by playing games with their portable game consoles, mobile phones, and tablet computers or watching information and videos on the Internet after waiting for time, but watching video information with their hand-held game consoles, mobile phones, and tablet computers for a long time , the hands and neck are easy to be overused and sore, and if you use game cons...
