  • Patent number: 11945744
    Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

  • Publication number: 20160085135
    Abstract: A single-channel phase conjugation apparatus includes a spatial light modulator and a single-channel optical sensing and generating unit. The spatial light modulator receives a light having a wavefront scattered by a scattering object. The single-channel optical sensing and generating unit senses a phase control wavefront of an output light focused by the spatial light modulator and outputs a light having a phase conjugation wavefront by changing a direction of the output light in a reverse direction depending on the phase control wavefront.

  • Patent number: 9163929
    Abstract: A tomographic image generation apparatus includes a light source unit configured to emit light to be used for scanning an object; an optical control unit configured to control a direction of propagation of light; an optical coupler configured to divide and combine incident light; a plurality of optical systems optically connected to the optical coupler; and a modulation and correction device configured to modulate and correct the light to be used for scanning the object. The modulation and correction device may be disposed between the optical control unit and the optical coupler, or may be included in an optical system that irradiates light onto the object among the plurality of optical systems. The modulation and correction device may only modulate light that is reflected to the object.
