Real-time T-ray system using line-beam and toric-lens

摘要

PURPOSE: A real-time T-ray system using line beam and toric lens applied therein are provided to inspect a large amount of objects under test in a short time. CONSTITUTION: A real-time T-ray system using line beam comprises a THz source(100), a reflective mirror(110), a toric lens(200), an image lens(250), and a line detector(300). The THz source transmits the signal beam of the THz frequency band. The toric lens receives the signal beam emitted from the source part and emits toward the object under test in the form of the line beam. The image lens forms the image of the line beam passing through the object under test from the toric lens. A line detecting part detects information about the object under test with the line beam emitted from the image lens and processes in the image signal.
