  • Publication number: 20200154988
    Abstract: An imaging device according to an embodiment of the present technology includes a first polarization section, a second polarization section, a rotation control section, and a generation section. The first polarization section irradiates a body tissue with polarization light of a first polarization direction. The second polarization section extracts a polarization component of a second polarization direction that intersects with the first polarization direction, from beams of reflection light that are the polarization light reflected by the body tissue. The rotation control section that rotates each of the first polarization direction and the second polarization direction while maintaining an intersection angle between the first polarization direction and the second polarization direction.

  • Publication number: 20180110414
    Abstract: The location of a tumor can be more easily and accurately recognized in the photodynamic diagnosis in which: a fluorescence image is produced by radiating excitation light having a specific wavelength from an excitation light source and capturing an image of fluorescence from a photosensitizer excited by the excitation light by a fluorescence imaging device; and an integrated image is produced by integrating the fluorescence image with a first image representing a positional relation of at least a part of a human body.

  • Publication number: 20180093104
    Abstract: The present invention provides a light irradiation method using a pulse laser, which can be applied to technology of PDD and/or PDT, and a system for treating a tumor, which has an enhanced tumoricidal effect. A light irradiation method of irradiating a cell into which a photosensitive compound capable of generating singlet oxygen has been incorporated with a pulse laser having a wavelength within a Soret band is provided. The pulse width of the pulse laser can be set to 100 psec or less, and the wavelength can be set to 405±10 nm. As the photosensitive compound capable of generating singlet oxygen, an agent for photodynamic therapy (PDT) or an agent for photodynamic diagnosis (PDD) can be used.

  • Publication number: 20150369742
    Abstract: Provided is a measuring apparatus including: a light source unit to emit pulsed laser light used for pump light and Stokes light that excite a molecular vibration of a sample; a Stokes light generating unit to modulate an intensity of the pulsed laser light and to generate Stokes light using the pulsed laser light having the modulated intensity; a time delaying unit to delay the pump light using the pulsed laser light or the Stokes light; a detecting unit to detect, by lock-in detection, light transmitted through the sample irradiated with the pump light and the Stokes light having a controlled time delay amount, or reflected light from the sample; and an arithmetic processing device to perform arithmetic processing on the basis of anti-Stokes light detected by the lock-in detection while controlling the intensity modulation and the time delay amount.

  • Publication number: 20150276608
    Abstract: According to an embodiment of the present disclosure, there is provided a biomolecule detection apparatus including a light emission unit, a measuring unit and an analysis unit. The light emission unit is configured to emit excitation light to living cells, the living cells having been in contact with an antitumor drug in advance. The measuring unit is configured to measure a Raman spectrum of the living cells. The analysis unit is configured to analyze whether or not the antitumor drug and a target biomolecule are bound with each other on the surface or inside of the living cells, based on the Raman spectrum.
