AI Technical Summary
Existing augmented reality optical devices have complex structures, resulting in large size and heavy weight, making them inconvenient for users to wear. They are also complex to manufacture, and the virtual image focal length adjustment requires additional operation, resulting in severe ghosting and affecting the field of view and light efficiency.
The optical structure employs a linear configuration, including a first reflection mechanism and a second reflection mechanism embedded within the optical mechanism. It transmits augmented reality image light to the pupil through multiple reflective elements, reducing ghosting and simplifying the manufacturing process.
Significantly reduces device size, thickness, and weight; expands the field of view; improves light efficiency; simplifies manufacturing processes; and provides clear virtual images and wide perspective.
