TERAHERTZ OPTICAL DEVICE AND ADJUSTMENT METHOD THEREFOR

摘要

A terahertz optical system comprising a terahertz light generator, a terahertz light detector, and a beam splitter or the like disposed between them. A rotating mechanism can rotate the beam splitter to a first rotation position where a probe light is directed toward a detector and to a second rotation position where a probe light is directed toward a generator. Alignment between a curved-surface mirror and the detector is adjusted so that a probe light condenses onto a proper position on the detector in a first rotation position status. Alignment between the curved-surface mirror and the generator is adjusted so that a probe light condenses onto the terahertz pulse light generation point on the generator in a second rotation position status.
