<p><P>PROBLEM TO BE SOLVED: To provide a terahertz imaging device capable of moving a terahertz source generating a terahertz wave having a variable frequency to the periphery of a measuring object, and measuring the terahertz wave. <P>SOLUTION: In this terahertz imaging device 100, a sensor head part 120 is separated from a body part 110 and connected through a composite cable 130, and only the sensor head part 120 can be moved and used. The body part 110 combines each laser light having each different wavelength emitted from two wavelength variable lasers 111, 112 by an optical coupler 115, and transmits the combined wave to the sensor head part 120 via an optical waveguide 131. The sensor head part 120 allows the transmitted combined wave to enter the terahertz source 121, and generates a terahertz wave having a frequency equivalent to a beat component of the combined wave. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
