Researchers at the Technical University of Munich (TU Munich) in Germany have developed a holographic imaging process that depicts the radiation of a Wi-Fi transmitter to generate three-dimensional images of the surrounding environment.
"Using this technology, we can generate a three-dimensional image of the space around the Wi-Fi transmitter, as if our eyes could see microwave radiation," says TU Munich researcher Friedemann Reinhard.
Although processes that enable the localization of microwave radiation already exist, the novelty of the new system is that an entire space can be imaged using holographic processing of Wi-Fi or cellphone signals to a spatial resolution of a few centimeters.
The researchers note future Wi-Fi frequencies will enable resolutions down to the millimeter range.
They say further advancement of the technology could aid in the recovery of victims buried under an avalanche or a collapsed building by providing a spatial representation of destroyed structures.
