  • Patent number: 9091665
    Abstract: When light beams of two different wavelengths applied from an excitation light source are made incident on a nonlinear optical crystal having a unique nonlinear coefficient, the nonlinear optical crystal generates THz waves resulting from difference frequency generation according to the nonlinear coefficient that the crystal itself has and SHG waves in which the light beams of two different wavelengths have been wavelength converted in accordance with the nonlinear coefficient. The generated THz waves pass through or are reflected from a sample and are detected by a THz detector. The SHG waves are detected by a SHG detector. A control unit acquires THz measurement values T from the THz detector, acquires SHG measurement values S from the SHG detector, and uses baseline THz measurement values TB and baseline SHG measurement values SB acquired without the sample to perform baseline correction using (T/S)/(TB/SB).

  • Patent number: 8969805
    Abstract: The base plate is transmissive to terahertz waves, and a sample is disposed at the base plate. In the conductive periodic structure, plural transmission portions that transmit terahertz waves are arrayed with a predetermined period. The conductive periodic structure is disposed apart from a position at which the sample is disposed. The waveguide includes a total reflection surface provided at a boundary face with the conductive periodic structure. The total reflection surface totally reflects incident terahertz waves, and the waveguide guides incident terahertz waves toward the total reflection surface. The magnitudes of one or more of a distance between the position at which the sample is disposed and the conductive periodic structure, a property of the base plate, and the predetermined period are set such that a dip showing a characteristic absorption is formed in a predetermined frequency region of a spectrum of terahertz waves.

  • Patent number: 8398937
    Abstract: A microchannel 4 for transporting a specimen S using capillary phenomenon includes an analysis chamber 6 having a cross-sectional area larger than those of portions located in front of and behind the analysis chamber 6 in the direction of flow, an inflow opening 5 through which the specimen S flows into the analysis chamber 6, and a discharge portion 7 through which the specimen S is discharged from the analysis chamber 6. The discharge portion 7 includes a pair of discharge openings 71a and 71b located opposite to each other with respect to the inflow opening 5. With this structure, impairment of transport of the specimen S due to the presence of a residual air bubble is avoided.
