Abstract :
In order to realize accuracy and convenience in the reflection THz-TDS, we propose and fabricate a movable THz-transparent sample holder to eliminate the misplacement errors between reference and sample, and make an analysis software to derive optical constants of a sample without approximation. Precise complex refractive indexes of pure water, and creams and gels used in medical examinations were obtained by the reflection measurement using these techniques.
