An ultrashort-pulse reflectometer (USPR) has been applied to the measurement of the edge density profile of the Large Helical Device at the National Institute for Fusion Science. The reflectometer signal is recorded directly using a high-speed digitizing scope, and is analyzed by means of a signal record analysis method to reconstruct the density profiles. This method has the advantage of using raw signal records instead of poorly localized frequency modes. The density profiles in the edge region are successfully determined and compared with those obtained by an FIR laser interferometer.
