摘要：

A new method of imaging supercurrent distribution in YBCO thin films has been proposed and demonstrated by using the THz radiation excited by femtosecond laser pulses. The characteristic distribution of the transport and persistent current in superconducting thin films is obtained and the result is discussed based on the Bean model.
