摘要： A projection lens system includes two lens elements being, in order from a magnification side to a reduction side along an optical path, a first lens element, and a second lens element. Each of the two lens elements has a magnification-side surface facing the magnification side and a reduction-side surface facing the reduction side. At least one of the magnification-side surface and the reduction-side surface of at least one of the two lens elements is aspheric.

摘要： A display apparatus and method, and a vehicle are disclosed. The display apparatus includes: an image generation module (10) including a spatial light modulator (103) that is configured to perform phase modulation on to-be-modulated image light, to generate modulated first image light and modulated second image light; and an image display module (20) that is disposed on a light emitting side of the image generation module (10). The image display module (20) includes a first diffusing screen (201) and a second diffusing screen (202). The first image light is projected on the first diffusing screen (201), and the second image light is projected on the second diffusing screen (202). A spatial position of the first diffusing screen (201) is different from a spatial position of the second diffusing screen (202). In this way, the spatial light modulator (103) is disposed in the image generation module (10), and a plurality of images with different spatial positions may be generated on the diffusing screens (201, 202), so that different types of information can be displayed, to meet a plurality of display requirements. Compared with a manner of disposing a plurality of image generation modules (10) to form images in different positions in space, this can save space, and is conducive to device miniaturization.

摘要： The marker according to the present invention comprises: a first surface which includes a plurality of convex surfaces; and a second surface. The second surface includes a plurality of first areas and a plurality of second areas, wherein the interval between the centers of the plurality of first areas is greater than the interval between the apexes of the plurality of convex surfaces. The plurality of first areas are arranged farther from the convex surfaces than a focal position of the plurality of convex surfaces. When external parallel light is made incident on the convex surfaces in an upper-lower direction, the width with respect to the first direction of a light bundle formed by the convex surfaces at a height at which the first areas are arranged is not more than the width with respect to the first direction of the first areas.
