  • Publication number: 20240085774
    Abstract: Provided include a beam modulation apparatus for modulating an input light field and a projection system containing the apparatus. The input light field has a first light field and a second light field, having a difference of 90° in their polarization states. The apparatus includes a PBS prism, a first LCOS panel and a second LCOS panel. The first and the second LCOS panel are respectively over a side surface of the PBS prism opposing to an optical incident surface and an optical exit surface. Each LCOS panel comprises a plurality of pixels over a reflective surface thereof, with each pixel controllably switched on or off such that a polarity state of a light beam reflected by a portion of the reflective surface corresponding thereto is changed or remains unchanged. This beam modulation apparatus can be applied in a projection system, such as a laser TV projection system.

  • Patent number: 11724949
    Abstract: Disclosed are a baffled integrated denitrifying and decarbonizing device with anaerobic bio-nests and a baffled integrated denitrifying and decarbonizing process with anaerobic bio-nests thereof. The wastewater with low carbon-nitrogen ratio first enters anaerobic chamber I, then enters anaerobic chamber II and chamber III to complete anaerobic decarbonization and denitrification. The chambers are provided with modified basalt fiber carrier media to enrich a large number of functional microorganisms, and improve the device in terms of anaerobic treatment efficiency. Fermentation liquid in chamber III then flows back to aerobic chamber IV to complete the nitrification process. Nitrified liquid enters chamber I and mixes with influent for further treatment, and effluent is finally discharged from chamber III. The clapboard and basalt fiber felt in chamber IV can retain and enrich autotrophic/heterotrophic nitrifying bacteria.
