    摘要： An optical system 10 includes a front group 11, a light-shielding member 4, and a rear group 12 that are arranged in this order in a direction from a side of an object toward a side of an image. The light-shielding member 4 has an opening elongated in a first direction. The front group 11 has aspherical surfaces 2 and 3, does not image the object at the opening in a first section parallel to the first direction, and forms an intermediate image of the object at the opening in a second section perpendicular to the first direction. The rear group 12 has a diffractive surface 5 that splits a light beam that passes through the opening into light beams at different wavelengths in the second section and focuses the light beams on different locations in the second section. Tilt angles of the aspherical surfaces 2 and 3 in the second section change in the first direction.

    摘要： The head-up display device (1) includes a light source (22); a condensing lens (23); a lens array (24) diffusing light from the condensing lens (23); a liquid-crystal display unit (10) emitting light from the lens array (24) as display light; and a reflecting member (30) reflecting the display light emitted from the liquid-crystal display unit (10) and projecting the display light on a windshield (103). The lens array (24) has, in an emitting surface (24b), a plurality of lens surfaces (24s) projecting toward the liquid-crystal display unit (10) and having an aspherical sectional shape, and, in the lens surface (24s), the curvature radius of a part (24t) emitting display light to be projected on an upper part (103t) of the windshield (103) is smaller than the curvature radius of a part (24u) emitting display light to be projected on a lower part (103u) of the windshield (103).

    摘要： An image combiner, also referred to as a combiner optic, of a near-eye display system or the like transmits enough light so a user can see remote objects in a "world view", while also reflecting enough light so the user can simultaneously see a projected image in a "projected" (augmented) view. The disclosed image combiners use two partial reflectors configured to form a wedged reflective cavity. In the display system, light from an imaging device follows a path to the user's eye that includes three reflections in the wedged cavity. By using this capability of the wedged cavity, the combiner optic can have a substantially reduced thickness, and lower profile, than a combiner optic that uses only one partial reflector and only one reflection in the optical path.

    摘要： A lens for an illumination device includes a lens 1 having a first surface 11 and a second surface 12 connected to each other along an annular curved line 14 which is composed of two symmetric curved lines 15. The two symmetric curved lines 15 are connected to each other at a first point 151 and a second point 153. Each of the two curved lines 15 has a middle point 152. The first surface 11 is a multiple-focus surface and located on the outer side of the lens 1. The patterns and paths of the light beams can be controlled by the first surface 11 of the lens 1.
