Abstract: A detection apparatus may include: An emitting component (301) emits a first beam. A light splitting component (3021) changes an optical path of a return optical signal from a detection region to obtain a first return optical signal and a second return optical signal, propagates the first return optical signal to a first detection component (3022), and propagates the second return optical signal to a second detection component (3023). The first detection component (3022) detects the first return optical signal to obtain a first electrical signal. The second detection component (3023) detects the second return optical signal to obtain a second electrical signal. The first electrical signal and the second electrical signal are for determining distance information of a target.

Abstract: 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.

Abstract: 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.
