The invention relates to the optical field and specifically relates to an eyeglass. The eyeglass is used for large visual field angle imaging and comprises an eyeglass body. The eyeglass is an optical waveguide sheet. The optical waveguide sheet is in a plate shape. A reflective projection array is embedded in the optical waveguide sheet. The reflective projection array is arranged on the right end of the optical waveguide sheet. Left side surfaces of reflective projections in the reflective projection array are respectively a reflective surface. A wedge-shaped reflective prism is arranged on the left end of the optical waveguide sheet. The wedge-shaped reflective prism is provided with a reflective surface and at least two light-transmitting surfaces. The reflective surface faces the right lower part of the optical waveguide sheet. One light-transmitting surface faces the optical waveguide sheet, and the light-transmitting surface is used as a light outgoing surface; and the other light-transmitting surface faces the outer side of two pieces of light-transmitting glass, and the light-transmitting surface is used as a light incoming surface. Compared with an existing imaging eyeglass, the visual field angle of the eyeglass is substantially improved, the visual field angle reaches 30 degrees, and the problem of a poor view caused by the too small visual field angle is solved for the user, so that the experience satisfaction degree of the user is improved.
Description
technical field [0001] The invention relates to the field of optics, in particular to lenses. Background technique [0002] Augmented reality technology is a new technology that integrates real world information and virtual world information, which can bring convenience to people in daily life. It can achieve a visual experience beyond the electronic screen. While displaying the information of the real world, it can also display the virtual information at the same time. The information of the digital world and the real world complement and superimpose each other, and the two are perfectly combined and presented in the eyes of users. . However, the existing augmented reality glasses generally have a too small field of view angle during use, resulting in poor visual field for users, thereby reducing user experience satisfaction. Contents of the invention [0003] The object of the present invention is to provide a lens for imaging with a large field of view to solve the ab...
