Publication number: 20240142307Abstract: A full-range imaging method doubles imaging range of conventional techniques by removing mirror images of an imaged object that limit conventional images to a “half-range” and that are caused in part by the loss of phase information in a detected signal. Phase information of the detected signal is reconstructed with an averaging technique based on a modulated phase induced in the detected signal during scanning.Type: ApplicationFiled: December 15, 2023Publication date: May 2, 2024Inventors: Xiang WEI, Tony KO
