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.
Claims17
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,
- wherein the terahertz wave oscillator further comprises a terahertz wave collector configured to:
- collect the terahertz wave;
- transmit the terahertz wave to a terahertz wave receiver;
- have an integrating sphere formed of a material capable of reflecting the terahertz wave;
- and
- have a predetermined radius of curvature.
A method for a water-proofing test using a device for the 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 the predetermined test area to determine whether water is penetrated into the predetermined test area,
- wherein the device for the water-proofing test comprises:
- a terahertz wave oscillator configured to generate and oscillate a terahertz wave;
- a terahertz wave detector configured to detect the terahertz wave reflected from the predetermined test area or transmitted through the predetermined test area;
- a controller configured to analyze a frequency spectrum of the terahertz wave to determine whether the water is penetrated into the predetermined test area,
- wherein the terahertz wave oscillator comprises a terahertz wave collector configured to:
- collect the terahertz wave;
- transmit the terahertz wave to a terahertz wave receiver;
- have an integrating sphere formed of a material capable of reflecting the terahertz wave;
- and
- have a predetermined radius of curvature.
