The present disclosure relates to apparatuses for display. An example display apparatus includes a picture generation unit, an imaging reflector, a detection unit, and at least one processor. The picture generation unit is configured to generate an image, and send image light of the image to the imaging reflector. The imaging reflector is configured to reflect the image light to generate a virtual image of the image. The detection unit is configured to collect first signal light transmitted through the imaging reflector, where the first signal light is light reflected by an eye of a user viewing the virtual image. The at least one processor is configured to determine a location of the eye of the user based on the first signal light collected by the detection unit, where a propagation direction of the image light reflected by the imaging reflector is parallel to a propagation direction of the first signal light.

Display apparatus, electronic device, and vehicle

One example power equalizer includes an input/output assembly, a multiplexer/demultiplexer, a pre-attenuation component, and a light beam modulator. The multiplexer/demultiplexer demultiplexes a first light beam into a plurality of first sub-wavelength light beams including a particular sub-wavelength light beam, and propagates the plurality of first sub-wavelength light beams to the pre-attenuation component. The pre-attenuation component makes the particular sub-wavelength light beam incident onto the light beam modulator at a preset angle. The light beam modulator performs angular deflection on the plurality of first sub-wavelength light beams to obtain a plurality of second sub-wavelength light beams. The pre-attenuation component then propagates the plurality of second sub-wavelength light beams to the multiplexer/demultiplexer. The multiplexer/demultiplexer multiplexes the plurality of second sub-wavelength light beams into a second light beam.

Power equalizer and adjustment method therefor

Embodiments of this application disclose a spectrum processing apparatus, which includes: a port assembly, a lens assembly, a dispersive assembly, a spatial light modulator (SLM), and a reflective element. Each port in the port assembly is configured to transmit an input first light beam to a lens corresponding to the port. Each lens in the lens assembly is configured to adjust a width of the first light beam to obtain a second light beam. The reflective element is configured to reflect the second light beam to the dispersive assembly. The dispersive assembly is configured to decompose the second light beam into a plurality of sub-wavelength light beams. The reflective element is further configured to reflect the plurality of sub-wavelength light beams to the SLM. The SLM is configured to modulate the plurality of sub-wavelength light beams, and reflect at least one modulated sub-wavelength light beam to the reflective element.

Spectrum processing apparatus and reconfigurable optical add-drop multiplexer

An optical communications apparatus, including a reconfigurable optical add/drop multiplexer, in which an optical deflection component may perform angle deflection on a plurality of first sub-wavelength light beams to obtain a plurality of second sub-wavelength light beams and a plurality of third sub-wavelength light beams, and propagate the plurality of second sub-wavelength light beams to a second optical switch array. A third wavelength dispersion component combines the plurality of second sub-wavelength light beams into a second light beam. A first output component outputs the second light beam from a dimension. A second wavelength dispersion component combines the plurality of third sub-wavelength light beams into a third light beam, and makes the third light beam incident to a third optical switch array. A second output component outputs the third light beam to drop a signal.

Optical communications apparatus and wavelength selection method

A polarization-dependent loss (PDL) determining method includes obtaining two groups of optical powers within first duration, selecting at least one group of target optical powers that satisfy a same power constraint from the two groups of optical powers, where each group of target optical powers includes a first target power and a second target power from the two groups of optical powers, and determining a PDL of the optical device based on the at least one group of target optical powers.
