PROBLEM TO BE SOLVED: To provide a biometric probe retainer allowing a sure measurement of an object in a living body by a light of an illumination power safe for living tissues; and a biometric apparatus using the same. SOLUTION: This biometric probe retainer 4 includes first and second body sections 10L and 10R worn to the ears, otoscopes 17L, 17R movably attached to the first and second body sections 10L and 10R, and bolts 24L and 24R for locking the movements of the otoscopes 17L and 17R. After inserting the otoscopes 17L and 17R into the earholes, the directions and angles of the otoscopes 17L and 17R are adjusted so as to optimize the relative position relationship between illumination or detection optical fiber probes 2 and 3 and the tympanic membranes.

Abstract:
PROBLEM TO BE SOLVED: To provide a biological measurement apparatus for measuring a location at which a light adsorber such as a tumor exists in the entire to-be-measured region. SOLUTION: The biological measurement apparatus 10 includes: a vessel 12 for holding an optical interface material 20; a light irradiation means for irradiating the to-be-measured region immersed in the optical interface material 20 with first and second lights having different wavelengths; a light detection means for detecting a diffusion light from the to-be-measured region; and a calculation/control section 14 for calculating internal information from an output signal of the light detection means. The wavelength λ1 of the first light is a wavelength at which an absorption coefficient of the to-be-measured region is substantially equal to an absorption coefficient of a medium. The wavelength λ2 of the second light is a wavelength at which the absorption coefficient of the to-be-measured region is larger than the absorption coefficient of the medium. The calculation/control section 14 calculates the internal information from the output signal related to the diffusion light of the first light, and calculates a boundary between the to-be-measured region and the optical interface material 20 from the output signal related to the diffusion light of the second light.

PROBLEM TO BE SOLVED: To safely and reliably detect the state of irradiating with a laser beam when irradiating an object with the laser beam. SOLUTION: The light irradiation apparatus 1 is provided with: a laser light source 10 which generates the laser beam; a light source 20 for light to be detected which generates the light to be detected of a prescribed wavelength; an optical fiber 30 which inputs the laser beam at its one end face 30a and emits it from the other end face 30b to irradiate the object 3, which inputs the light to be detected at the one end face 30a, and which has an FBG (Fiber Bragg Grating) 32 reflecting light of a prescribed wavelength formed in the vicinity of the other end face 30b; a light detector 50 which detects intensity of the light to be detected which is reflected by the FBG 32 and emitted from the one end face 30a; and a signal processing part 60 which detects the state of irradiating the object 3 with the laser beam based on the intensity of the detected light to be detected. The laser beam generated from the laser light source 10 is other than the light of the wavelength reflected by the FBG 32. COPYRIGHT: (C)2008,JPO&INPIT
