摘要
A new type of terahertz (THz) radiation imaging has been proposed and demonstrated. The supercurrent distributions were visualized by detecting the backscattered THZ radiation from optically excited high-temperature superconductors. The supercurrent distributions were clearly observed in 100- and 500-nm-thick YBa2Cu3O7-delta films in the remanent state. Our system has performance similar to the system With transmission configuration.
