Abstract
A cylindrical shell detection method includes generating a first and a second terahertz transmitting electromagnetic waves; detecting a plurality of first terahertz reflected electromagnetic waves reflected by the first terahertz transmitting electromagnetic wave incident in a plurality of inner interface layers of a cylindrical shell; detecting a plurality of second terahertz reflected electromagnetic waves reflected by the second terahertz transmitting electromagnetic wave incident in a plurality of outer interface layers of a cylindrical shell; measuring a plurality of first characteristic signals according to the first terahertz transmitting electromagnetic waves and the first terahertz reflected electromagnetic waves to determine a plurality of first characteristics of the plurality of inner interface layers; and measuring a plurality of second characteristic signals according to the second terahertz transmitting electromagnetic waves and the plurality of second terahertz reflected electromagnetic waves to determine a plurality of second characteristics of the plurality of inner interface layers.
