Holographic Camera Peers Through Fog, Around Corners

Facebook Twitter LinkedIn Email
EVANSTON, Ill., Dec. 28, 2021 — A high-resolution camera that can capture images around corners and through scattering media, such as skin, fog, and potentially the human skull, combines high temporal resolution, a small probing area, and a large angular field of view into a single device. A team of researchers at Northwestern University has introduced the device, which uses a holographic method and reconstructive algorithm to reveal hidden objects. Called synthetic wavelength holography, the method indirectly scatters coherent light onto hidden objects, which then scatters again and travels back to a camera. From...Read full article
