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.

Abstract: A light beam processing apparatus and a light beam processing method are described that improve utilization of the light beam. The light beam processing apparatus includes a light source, a polarization converter, and a polarizer. The light source is configured to provide a first light beam. The first light beam includes a second light beam in a first polarization state and a third light beam in a second polarization state. The polarizer is configured to transmit the second light beam and reflect the third light beam to the polarization converter. The polarization converter is configured to convert the third light beam into a fourth light beam. The fourth light beam is utilized for obtaining a fifth light beam in the first polarization state. The polarizer is further configured to transmit the fifth light beam.

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.
