Abstract: An optical system. A light source component generates a light beam. A light adjustment component adjusts a ratio of the S-polarized light and a ratio of the P-polarized light in the light beam. A first polarization beamsplitter mirror component splits a light beam adjusted by the light adjustment component into a first light beam and a second light beam, where the first light beam is a light beam of the S-polarized light, and the second light beam is a light beam of the P-polarized light. The first lens component projects the first light beam or a modulated first light beam to a first region. The second lens component projects the second light beam or a modulated second light beam to a second region.

Abstract: A display system is provided. The display system includes a windshield, a picture generation unit (PGU), and an optical element, where the windshield includes a first windshield surface and a second windshield surface. The PGU projects a light beam corresponding to a picture generated by the PGU to the optical element. The optical element directs the light beam to the first windshield surface. The first windshield surface refracts the light beam to the second windshield surface, and reflects the light beam to a human eye for receiving. The first windshield surface refracts a light beam reflected from the second windshield surface to the human eye for receiving. After reflection by the first windshield surface, the light beam forms a first virtual image with the picture. After reflection by the second windshield surface and refraction by the first windshield surface, the light beam forms a second virtual image with the picture.

Abstract: An optical processing apparatus and an optical system. The apparatus includes an input port, an optical path conversion assembly, an LCoS assembly, and an output port. The input port receives a first light beam. The optical path conversion assembly performs chromatic dispersion on the first light beam to obtain a second light beam, the second light beam being a single-wavelength light beam. The LCoS assembly diffracts the second light beam to obtain diffracted light of the second light beam. The diffracted light of the second light beam includes 0-order diffracted light and +1-order diffracted light. The optical path conversion assembly transmits the diffracted light of the second light beam, and converges the +1-order diffracted light to the output port. The output port collimates and outputs the received +1-order diffracted 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.
