Abstract
A high-speed device, for inspecting a large area of an object, which includes: a terahertz wave generation portion configured to generate a terahertz wave; a ring beam forming portion configured to form a ring beam by using the terahertz wave incident from the terahertz wave generation portion; a rotary mirror configured to reflect the ring beam formed by the ring beam forming portion while rotating to allow the ring beam to be incident on an inspection target object; and a detector configured to detect a ring beam generated from the inspection target object.
