LIVING-BODY INFORMATION MEASURING DEVICE AND LIGHT-EMITTING ELEMENT
First Claim
1. A living-body information measuring device comprising:
- a first light-emitting unit that emits a single-mode laser beam;
a second light-emitting unit that emits a multi-mode light beam or an LED light beam;
a light-receiving element that receives reflected or transmitted light beams reflected or transmitted by a living body when the first light-emitting unit and the second light-emitting unit emit the beams toward the living body;
a control unit that controls light-emission periods of the first light-emitting unit and the second light-emitting unit; and
a measurement unit that measures a plurality of types of living-body information about the living body by using each of the reflected or transmitted light beams that are successively received by the light-receiving element.
