Abstract: An adsorption evaluation apparatus includes a measurement unit and an evaluation unit. The measurement unit irradiates a porous framework being an evaluation object with a terahertz wave, and performs measurement of a refractive index or a real part of a complex permittivity of the porous framework based on the terahertz wave which interacted with the porous framework. The evaluation unit performs evaluation of adsorption of a substance on the porous framework based on the refractive index or the real part of the complex permittivity of the porous framework measured by the measurement unit.

Abstract: A measurement auxiliary member is placed on an arrangement surface of a prism. A measurement object is placed on an upper surface of the measurement auxiliary member. The measurement auxiliary member totally reflects the terahertz wave input from a lower surface by the upper surface and outputs the totally-reflected terahertz wave from the lower surface. A main pulse of a terahertz wave totally reflected by the upper surface of the measurement auxiliary member without multiply-reflected inside any optical element on an optical path of the terahertz wave, and a noise pulse of a terahertz wave multiply-reflected inside any optical element on the optical path and reflected on an interface between the prism and the measurement auxiliary member, are temporally separated from each other when detecting a correlation by a terahertz wave detection element.

Abstract: In this electric field vector detection method, an electro-optic crystal, where a (111) surface of an optical isotropic medium is cut out, is used as a terahertz wave detection element. The method includes: causing polarization of probe light of ultrashort pulsed light to be circular polarization; allowing the probe light having circular polarization to enter the terahertz wave detection element and probing the terahertz wave; modulating the probe light, having probed the terahertz wave, by a rotating analyzer and detecting the modulated probe light by a photodetector; performing lock-in detection of a detection signal from the photodetector by a lock-in detector using a frequency based on a rotational frequency of the rotating analyzer as a reference signal; and detecting an electric field vector of the terahertz wave based on a detection signal from the lock-in detector.
