  • Patent number: 11947162
    Abstract: The present invention relates to a guiding apparatus for an imaging light path and a guiding method thereof. The guiding apparatus comprises at least one light-projection system to project at least one visible light beam and at least one light-guiding device disposed corresponding to the light-projection system. The light-guiding device has a first end, a second end, and a light path disposed between the first end and the second end. The visible light beam projected from the light-projection system is received at the first end and guided to an image-receiving object, including but not limited to the user's eyes, out of the second end through the light path to form a real or virtual image. The effects of high brightness of the visible light beam arriving at the image-receiving object, low consumption of light energy, and improved installation flexibility in a space-limited apparatus can be obtained.
