LIVING-BODY COMPONENT MEASURING APPARATUS
First Claim
1. A living-body component measuring apparatus that measures a component of an inner tissue of a living body serving as an object to be measured by emitting laser light having two or more wavelengths from a light source and measuring reflected light of the laser light from the inner tissue of the living body, the living-body component measuring apparatus comprising:
- a beam splitter that changes optical paths of a part of the laser light emitted from the light source and the reflected light from the inner tissue of the living body;
a reference-light measuring unit that measures, as reference light, the part of the laser light emitted from the light source and having the optical path changed by the beam splitter;
a reflected-light measuring unit that measures the reflected light reflected by the inner tissue of the living body and having the optical path changed by the beam splitter; and
an analysis unit that analyzes the inner tissue of the living body by measuring a spectrum of the reflected light or the reference light.

Abstract
A living-body component measuring apparatus measures a component of an inner tissue of a living body serving as an object to be measured by emitting laser light having two or more wavelengths from a light source and measuring reflected light of the laser light from the inner tissue of the living body. The living-body component measuring apparatus includes a beam splitter that changes optical paths of a part of the laser light and the reflected light, a reference-light measuring unit that measures, as reference light, the part of the laser light having the optical path changed by the beam splitter, a reflected-light measuring unit that measures the reflected light having the optical path changed by the beam splitter, and an analysis unit that analyzes the inner tissue by measuring a spectrum of the reflected light or the reference light.

4. A living-body component measuring apparatus that measures a component of an inner tissue of a living body serving as an object to be measured by emitting laser light having two or more wavelengths from a light source and measuring reflected light of the laser light from the inner tissue of the living body, the living-body component measuring apparatus comprising:
-
a branching unit that branches the laser light emitted from the light source; a reference-light measuring unit that measures, as reference light, one part of the laser light branched by the branching unit; a reflected-light measuring unit that measures the other part of the laser light branched by the branching unit and serving as the reflected light from the inner tissue of the living body; and an analysis unit that analyzes the inner tissue of the living body by measuring a spectrum of the reflected light or the reference light serving as the part of the laser light branched by the branching unit. - View Dependent Claims (16)

5. A living-body component measuring apparatus that measures a component of an inner tissue of a living body serving as an object to be measured by emitting laser light having two or more wavelengths from a light source and measuring reflected light of the laser light from the inner tissue of the living body, the living-body component measuring apparatus comprising:
-
a first beam splitter that transmits one part of the laser light emitted from the light source and changes an optical path of the other part of the laser light; a second beam splitter that changes an optical path of the part of the laser light incident through the first beam splitter, transmits the other part of the laser light, and changes an optical path of the reflected light from the inner tissue of the living body; a reference-light measuring unit that measures, as reference light, the other part of the laser light emitted from the light source and having the optical path changed by the first beam splitter; a reflected-light measuring unit that measures the reflected light reflected by the inner tissue of the living body and having the optical path changed by the second beam splitter; and an analysis unit that analyzes the inner tissue of the living body by measuring a spectrum of the reflected light or the reference light having the optical path changed by the first beam splitter. - View Dependent Claims (17)
