  • Patent number: 10582154
    Abstract: A picture presentation system 1 presents a user U with a picture where a virtual image Di is created in a space in front of the user U. The picture presentation system 1 includes a hologram mirror 10 configured to reflect a picture composed of light of a specific wavelength at an angle different from an angle of incidence and transmit light other than the light of the specific wavelength, and a screen 20 configured to display the picture toward the hologram mirror. The hologram mirror 10, being placed opposite to the user U, reflects the picture from the screen 20 in such a way that the user U can visually recognize the virtual image Di of the picture at a position on the opposite side from the user U across the hologram mirror 10 (arrow AR1).

  • Patent number: 10436632
    Abstract: A terahertz image measurement device includes a terahertz detection sensor, a magnetic field generating unit, and a measurement control unit. The sensor detects near-field light of terahertz light emitted from a sample. The magnetic field generating unit has a coil disposed around the sample and the sensor, and wound to surround the optical axis of terahertz light irradiated on the sensor, and applies to the sensor a magnetic field generated by allowing an electric current to flow through the coil. The measurement control unit changes a value of the electric current flowing through the coil, sets a strength of the magnetic field to a magnetic field value for which a detection signal level of the terahertz light detected by the sensor increases prominently, and allows the magnetic field value to conform to a specific frequency of the terahertz light.
