Disclosed are a lens unit, an optical lens, an illumination module, a vehicle light, and a vehicle. The lens unit comprises a light incident portion (1) having first unidirectional collimation and a light emergent portion (2) having second unidirectional collimation, so as to form an asymmetric light shape. The lens unit can meet the requirement of the anisotropy of the illumination light shape of the vehicle light so as to form the asymmetric light shape, thereby meeting the requirement for a narrow and long model.

Methods, apparatus, systems, and articles of manufacture are disclosed to map multi-display positions. An example apparatus includes processor circuitry to cause a first display to present a first image, cause a second display to present a second image, detect a first reflection based on the first image, detect a second reflection based on the second image, and determine a position of the first display relative to the second display based on the first reflection and the second reflection.

Methods and systems for measuring structural and material characteristics of semiconductor structures based on combined x-ray reflectometry (XRR) and x-ray photoelectron spectroscopy (XPS) are presented herein. A combined XRR and XPS system includes an x-ray illumination source and x-ray illumination optics shared by both the XRR and XPS measurement subsystems. This increases throughput and measurement accuracy by simultaneously collecting XRR and XPS measurement data from the same area of the wafer. A combined XRR and XPS system improves measurement accuracy by employing XRR measurement data to improve measurements performed by the XPS subsystem, and vice-versa. In addition, a combined XRR and XPS system enables simultaneous analysis of both XRR and XPS measurement data to more accurately estimate values of one of more parameters of interest. In a further aspect, any of measurement spot size, photon flux, beam shape, beam diameter, and illumination energy are independently controlled.

The light source performs irradiation with light. The light modulation portion modulates the light from the light source. The first mirror, the second mirror, the third mirror, and the fourth mirror reflect an optical image modulated by the light modulation portion.

A see-through display including a polarized reflective pinhole mirror display. The pinhole mirror display includes a plurality of tiny switchable polarized mirrors. The respective polarized mirrors individually reflect impinging light from an illuminator, and guide the respective portion of light into a pupil of an eye. A reflective optically powered surface reflects light from the illuminator. Each mirror has a first polarization and reflects a portion of light and produces a picture element (pixel) that forms a virtual image seen by the eye of the user. A user may view the reflected virtual image having the first polarization from the illuminator, as well as the image from the real world via a rear substrate that has a second polarization. Although the mirrors are very small, human eyes can still detect the mirrors if they are not polarized. The mirrors and other components are polarized so that the eye can see the real world filtered with the second polarization, but not the mirrors having a different first polarization.
