Abstract :
Summary from only given. We demonstrate the simple, noncontact and simultaneous measurement for thickness and water content of black ink films using THz radiation. The experimental setup was shown To generate intense THz radiation, the excitation laser irradiated InAs with 70-degrees-incidence angle. The transmitted THz radiation was collimated by a 10-cm off-axis parabolic mirror, lead to polarizing Michelson interferometers, and detected by a bolometer.
