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. The generation section that generates an image signal of the body tissue on the basis of the polarization component of the reflection light extracted by the second polarization section in accordance with rotation operation performed by the rotation control section.

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.
