Abstract: A terminal roaming method, an apparatus, and a wireless local area network are disclosed, and belong to the field of WLAN technologies. A session parameter used when a terminal performs data exchange with an original associated AP is migrated to a roaming target AP. After the terminal is associated with the roaming target AP, the roaming target AP can continue data exchange with the terminal based on the migrated session parameter, and the terminal can also continue data exchange with the roaming target AP based on the session parameter used when the terminal performs data exchange with the original associated AP. The terminal and the roaming target AP do not need to perform session negotiation again, to shorten a data service recovery time required after a roaming handover of the terminal, and reduce a service transmission delay. This improves smoothness of roaming handover of the terminal.

Abstract: A method is provided for constructing a three-dimensional hyperspectral image using compressive sensing. The method includes: configuring on/off state of each mirror in an array of micromirrors in accordance with a pattern; capturing image data of a scene from a first point of view using a first photodetector; and capturing image data of the scene from second point of view using a second photodetector, where second point of view differs from the first point of view. The steps are repeated to obtain a series of measurement samples, where the array of micromirrors is configured in accordance with a pattern that differs amongst each measurement samples. By choosing different photodetectors with different band gap nanomaterials, the first and second photodetectors detects photons in the electromagnetic spectrum. As a result, the three-dimensional image also carry the spectrum information of the scene.
