Abstract: A spatial light modulator and a projection system are provided. The spatial light modulator includes a substrate layer, a first electrode layer, a first metasurface layer, a phase change material layer, a second electrode layer, and a first flat layer. The first electrode layer and the second electrode layer are respectively disposed on opposite sides of the substrate layer and the first flat layer that are parallel to each other, and the first metasurface layer and the phase change material layer are disposed between the first electrode layer and the second electrode layer. The first metasurface layer includes at least two metasurface units that are sequentially arranged, and a resonance frequency of each metasurface unit corresponds to a preset incident optical wavelength of each metasurface unit. The spatial light modulator performs phase modulation on incident light through the first metasurface layer and the phase change material layer.

Abstract: An optical display element includes a plurality of stripes. The plurality of stripes are arc-shaped and have a same bending direction, and the plurality of stripes are configured to reflect operating light of the optical display element, so that the operating light is imaged. Each stripe of the plurality of stripes includes a plurality of resonance elements, and the operating light generates a resonance effect in one or more of the resonance elements.

Abstract: This application provides an optical combiner and a related device for augmented reality. The optical combiner includes a transparent substrate and a metasurface layer. The metasurface layer is disposed on a surface of the transparent substrate. The metasurface layer includes a plurality of metasurface units arranged two-dimensionally. A spacing between two adjacent metasurface units in the plurality of metasurface units gradually changes along one or two dimensions, and a relative angle between any two adjacent metasurface units is not zero. The optical combiner can increase an ambient light transmittance and increase uniformity and a field of view of an image.

Abstract: A resource negotiation method, a device, and a system for D2D communication are provided. The method comprises: a second base station acquires an available channel resource of a first device, where the first device is connected with a first base station; the second base station allocates, on the basis of an available channel resource of a second device connected with self and of the available channel resource of the first device, a D2D communication resource for D2D communication between the first device and the second device; and the second base station notifies the second device of the allocated D2D communication resource and notifies the first device via the first base station. The resource negotiation method, the device, and the system for D2D communication implement resource negotiation for successful D2D communication between devices under different base stations or access points.
