Title:
HIGH-RESOLUTION TERAHERTZ WAVE CONCENTRATING MODULE, SCATTERED LIGHT DETECTION MODULE, AND HIGH-RESOLUTION INSPECTION APPARATUS USING TERAHERTZ BESSEL BEAM
Document Type and Number:
WIPO Patent Application WO/2018/084355
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a terahertz wave concentrating module can comprise: a first lens for changing a terahertz wave, which is emitted while a terahertz Bessel beam penetrates an object to be inspected, so as to have a small angle; and a second lens for concentrating, on a detector, the terahertz wave having passed through the first lens.
