摘要： A device and method for estimating the elevation angle of one or more objects surrounding a user terminal include a convex image-reflecting surface, a transparent sighting surface disposed above the convex image-reflecting surface, and an elevation limit marking formed on or in the sighting surface. The elevation limit marking generates a reflected image in the convex image-reflecting surface that defines an elevation angle above a horizon of the earth that the one or more objects in a field of view of the convex image-reflecting surface must remain below so that the user terminal has an unobstructed view of the sky in all azimuthal directions.

By performing parameter refining on the fs2 that influences the optical amplification effect, the module can keep a small overall thickness while obtaining a large optical amplification effect, and it can be applied in a small-size VR device, so that the VR device can realize a wide field angle, a large eyebox and a high-quality imaging effect, and hence a better user experience.
