Abstract: The present invention provides an optical imaging structure, which comprises a windshield. The windshield includes a first glass layer and a second glass layer spaced with the first glass layer by a fixed distance. A horizontal curvature of the first glass layer and the second glass layer is greater than 3.5 meters. A vertical curvature of the first glass layer and the second glass layer is greater than the horizontal curvature. When an optical imaging device works with the windshield for imaging, the double-image phenomenon may be reduced.
