Wi-Fi holography: Generate a 3D image of space using stray Wi-Fi signals

Scientists at the Technical University of Munich (TUM) have developed a holographic imaging process that depicts the radiation of a Wi-Fi transmitter to generate three-dimensional images of the surrounding environment. Industrial facility operators could use this to track objects as they move through the production hall. Set-up of the WLAN-holography experiment Just like peering through a window, holograms project a seemingly three-dimensional image. While optical holograms require elaborate laser technology, generating holograms with the microwave … More
