Abstract EN
A Brewster angle reflection imaging apparatus is demonstrated which is capable of detecting hidden water-filled voids in a rubber tile sample.
This imaging application simulates a real-world hull inspection problem for Royal Canadian Navy Victoria-class submarines.
The tile samples represent a challenging imaging application due to their large refractive index and absorption coefficient.
With a rubber transmission window at approximately 80 GHz, terahertz (THz) sensing methods have shown promise for probing these structures in the laboratory.
Operating at Brewster’s angle allows for the typically strong front surface reflection to be minimized while also conveniently making the method insensitive to air-filled voids.
Using a broadband THz time-domain waveform imaging system (THz-TDS), we demonstrate satisfactory imaging and detection of water-filled voids without complicated signal processing.
Optical properties of the tile samples at low THz frequencies are also reported.
