摘要： PROBLEM TO BE SOLVED: To provide a portable-sized terahertz wave generation device and generation method by controlling a time lag of two laser beams driven by a single laser light source for excitation.
SOLUTION: The terahertz wave generation device is equipped with: a single laser light source 2 for excitation; a branching optical system 3 which branches light impinging from the light source 2 into two; a laser light source 4 of a first frequency, which generates a laser beam 7 at the first frequency for terahertz wave generation in response to incidence of one of two branched laser beams for excitation; a laser light source 5 of a second frequency, which generates a laser beam 8 at the second frequency for terahertz wave generation in response to incidence of the other of two branched laser beams for excitation; a multiplexing optical system 6 which multiplexes the laser beam 7 and the laser beam 8; and a crustal 9 for terahertz wave generation on which the laser beam at the first frequency and the laser beam at the second frequency, which are multiplexed, impinge from the multiplexing optical system 6. A terahertz wave 25 is generated by difference frequency mixing of the laser light 7 at the first frequency and the laser light 8 at the second frequency by the crystal 9 for terahertz wave generation.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for simple and high-sensitivity detection of the components of a calculus and those of excretions, such as urine from a living body, which are necessary for diagnosis and treatment, and quantitatively analyzing them. SOLUTION: Measurement on absorption spectrum in a terahertz domain is applied to an analysis of living-body excretory substances, such as components of calculus and substances in urine. By comparing them with one another, a simple, high-speed, and high-reliability pathological diagnosis is realized. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a tooth decay detection method and device for detecting an early tooth decay with sensitivity, accuracy, and safety. SOLUTION: A terahertz spectroscope capable of frequency sweeping or a terahertz analyzer generating only a specific wavelength is applied to a decayed tooth diagnosis to detect a tooth decay mainly from crystallinity evaluation or from crystal defects caused by changes in the composition. Nondestructive, noninvasive, and quantitative diagnosis is realized through evaluation by using the reflection intensity characteristic, in particular, of the tooth surface.
