Abstract
Official abstract text for this publication.
A measurement apparatus includes a first light emission unit that emits light having a first wavelength, a second light emission unit that emits light having a second wavelength of which an arrival depth with respect to a measurement site exceeds the arrival depth of the light having the first wavelength, a light reception unit that generates a detection signal corresponding to a light reception level of light arriving from the measurement site, and an analysis unit that acquires biological information corresponding to the detection signal. The first light emission unit, the second light emission unit, and the light reception unit are installed on a detection surface facing the measurement site, and a distance between the first light emission unit and the light reception unit exceeds a distance between the second light emission unit and the light reception unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . A measurement apparatus comprising: a first light emission unit that emits light having a first wavelength; a second light emission unit that emits light having a second wavelength of which an arrival depth with respect to a measurement site exceeds the arrival depth of the light having the first wavelength; a light reception unit that generates a detection signal corresponding to a light reception level of light arriving from the measurement site; and an analysis unit that acquires biological information corresponding to the detection signal, wherein the first light emission unit, the second light emission unit, and the light reception unit are installed on a detection surface facing the measurement site, and a distance between the first light emission unit and the light reception unit exceeds a distance between the second light emission unit and the light reception unit. 2 . The measurement apparatus according to claim 1 , wherein the first light emission unit, the second light emission unit, and the light reception unit are collinearly positioned. 3 . The measurement apparatus according to claim 1 , wherein the light reception unit includes a first light reception unit receiving light which is emitted from the first light emission unit and passes through the measurement site, and a second light reception unit receiving light which is emitted from the second light emission unit and passes through the measurement site, and wherein a distance between the first light emission unit and the first light reception unit exceeds a distance between the second light emission unit and the second light reception unit. 4 . The measurement apparatus according to claim 3 , wherein the first light emission unit, the second light emission unit, the first light reception unit, and the second light reception unit are collinearly positioned. 5 . The measurement apparatus according to claim 4 , wherein the first light emission unit and the first light reception unit are positioned between the second light emission unit and the second light reception unit. 6 . The measurement apparatus according to claim 3 wherein a straight line passing through the first light emission unit and the first light reception unit and a straight line passing through the second light emission unit and the second light reception unit intersect each other. 7 . The measurement apparatus according to claim 1 , wherein the light having the first wavelength is near infrared light, and wherein the light having the second wavelength is red light. 8 . The measurement apparatus according to claim 1 , wherein the light having the first wavelength is green light, and wherein the light having the second wavelength is near infrared light or red light. 9 . A detection device which generates a detection signal used for generating biological information, the detection device comprising: a first light emission unit that emits light having a first wavelength; a second light emission unit that emits light having a second wavelength of which an arrival depth with respect to a measurement site exceeds the arrival depth of the light having the first wavelength; and a light reception unit that generates a detection signal corresponding to a light reception level of light arriving from the measurement site, wherein the first light emission unit, the second light emission unit, and the light reception unit are installed on a detection surface facing the measurement site, and a distance between the first light emission unit and the light reception unit exceeds a distance between the second light emission unit and the light reception unit.
