    Abstract: A head-up display for a transportation vehicle. The head-up display includes an imaging unit for generating an image, and an optical system for projecting the image onto a projection surface. The optical system includes at least a first mirror, a curved second mirror arranged adjacent to the first mirror, and a selectively reflective element configured in an optical path between the first mirror and the second mirror. The optical system is configured such that light emitted from the imaging unit is directed to pass through the selectively reflective element, reflected off the first mirror towards the selectively reflective element, reflected by the selectively reflective element towards the second mirror, and reflected by the second mirror towards the selectively reflective element, and passed through to be directed to the projection surface.

    Abstract: A reflector (10), a method for manufacturing the same, a lens module (001), and an electronic device are provided, and pertain to the field of optical technologies. The reflector (10) uses a silicon-based substrate (101) with a planar structure as a base material, which can effectively reduce a volume and mass of the reflector (10) when compared with a right triangular prism. In addition, an included angle (γ) between a second side surface (1d) and a second surface (1b) of the silicon-based substrate (101) is designed as an obtuse angle, to ensure that after the reflector (10) is arranged in an inclined manner, a right angle protruding outward is not formed between the second side face (1d) and the second surface (1b).

    Abstract: A process for manufacturing a mirror includes preparing a mirror core by successively depositing a plurality of layers of a core material to form a core structure; and bonding, using a bonding material, the mirror core to a front polishable faceplate and a back faceplate. A mirror includes a mirror core including a plurality of layers of a core material; a front polished faceplate; and a back faceplate. The front polished faceplate and the back faceplate are bonded to the mirror core with a bonding material.
