Abstract
The present disclosure provides a device for a water-proofing test, the device including: a terahertz wave oscillator configured to generate and oscillate a terahertz wave; a terahertz wave detector configured to detect the terahertz wave reflected from a predetermined test area of a test target or transmitted through the predetermined test area; and a controller configured to analyze a frequency spectrum of the terahertz wave to determine whether water is penetrated into the predetermined test area.
Claims18
A device for a water-proofing test, the device comprising:
- a terahertz wave oscillator configured to generate and oscillate a terahertz wave;
- a terahertz wave detector configured to detect the terahertz wave reflected from a predetermined test area of a test target or transmitted through the predetermined test area;
- and
- a controller configured to analyze a frequency spectrum of the terahertz wave detected by the terahertz wave detector to determine whether water is penetrated into the predetermined test area.
A method for a water-proofing test, the method comprising steps of:
- (a) applying heat to a predetermined test area of a test target such that water penetrating into the predetermined test area is phase-transformed into water vapor;
- (b) irradiating a terahertz wave to the predetermined test area;
- and
- (c) analyzing the terahertz wave reflected from the predetermined test area or transmitted through predetermined the test area to determine whether water is penetrated into the predetermined test area.
