This application discloses a spatial light modulator, driving method, free-space optical antenna, device, and system, relating to the field of free-space optical communication technology. The spatial light modulator includes a first substrate, a first electrode, a liquid crystal layer, a second electrode, and a second substrate. The first electrode is a planar electrode, and the second electrode includes multiple sub-electrodes spaced apart from each other. The multiple sub-electrodes are arranged sequentially from the inside to the outside around a center. When different driving voltages are applied to the first electrode and the sub-electrodes respectively, the liquid crystal material in the liquid crystal layer flips under the action of the electric field, resulting in different equivalent dielectric constants of the liquid crystal material. This allows the spatial light modulator to adjust the intensity and phase of the incident light beam to modulate different types of light beams, achieving adaptive switching of light beam types. In particular, it can achieve adaptive switching of different types of light beams in a sharp beam, improving anti-turbulence capability and enhancing the stability of the communication link.

This utility model discloses a smoke exhaust pipe, a smoke exhaust assembly, and an integrated stove, belonging to the field of integrated stoves. It includes a pipe body with cross-sectional shapes on a plane perpendicular to its smoke exhaust direction. Each cross-sectional shape is parallel to a common direction, and the projected length of each cross-sectional shape along the common direction is less than or equal to the projected length of its corresponding plane in other directions. The smoke inlet of the pipe body is a first smoke inlet, and a connecting structure for connecting to the exhaust hood is also provided at the first smoke inlet of the pipe body. The technical advantage of this utility model is that the smoke exhaust pipe only occupies a small portion of the width used to conceal the cabinet, allowing for a larger remaining usable width in the cabinet, indirectly increasing the usable storage space of the cabinet.
