OPTICAL COMPONENT FOR TRANSMITTING TERAHERTZ WAVE, TERAHERTZ WAVE OPTICAL SYSTEM, AND TERAHERTZ BAND WAVE PROCESSOR AND TERAHERTZ BAND WAVE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a terahertz band wave processor which has excellent transmission characteristics of a terahertz band wave, whose cost is low, and which can be easily manufactured.;SOLUTION: The terahertz band wave processor has a terahertz wave generator 10 which generates a prescribed terahertz wave and an optics optical surface constituted of highly functional resin provided on the front surface in the traveling direction of the generated terahertz wave. As a more specific example, an optical semi-transmission plate 4 is constituted as the optics optical surface. An optical axis between the plate 4 and the terahertz wave generator 10 is regulated by a first optical transmission regulator 1, the terahertz wave on the optical axis is transmitted and light to be made incident with a prescribed incident angle is reflected by the plate 4. Furthermore, second optical transmission regulators 2, 3 are set on the optical axis between the plate 4 and an Si bolometer. Prescribed visible light is made incident on the plate 4 as pilot light 12, and reflected by the plate 4, and the optical axis of the reflected visible light is superimposed on the optical axis of the terahertz wave 11. Consequently, the optical axis of the terahertz wave 11 is simulatively made visible by the visible light.;COPYRIGHT: (C)2005,JPO&NCIPI
