PHYSIOLOGICAL INFORMATION MEASURING APPARATUS
First Claim
1. A physiological information measuring apparatus comprising:
- a first detection unit, comprising a first light emitting unit and a first light receiving unit, wherein the first light emitting unit and the first light receiving unit are separated from one another by a first distance;
a second detection unit, comprising a second light emitting unit and a second light receiving unit, wherein the second light emitting unit and the second light receiving unit are separated from one another by a second distance, different than the first distance; and
a measuring unit that measures the physiological information of a user based on light received by the first light receiving unit and light received by the second light receiving unit, wherein wavelengths of the first light emitting unit and the second light emitting unit are approximately 470 nm to approximately 610 nm, and wherein the first distance is from approximately 2 mm to approximately 4 mm.

Abstract
A physiological information measuring apparatus includes a first detection unit, having a first light emitting unit and a first light receiving unit, separated from one another by a first distance. A second detection unit of the physiological information measuring apparatus has a second light emitting unit and a second light receiving unit, separated from one another by a second, different distance. Alternatively, the second detection unit shares the first light emitting unit with the first detection unit and has a second light receiving unit. Alternatively, the second detection unit shares the first light receiving unit with the first detection unit and has a second light emitting unit. A measuring unit of the physiological information measuring apparatus measures the physiological information of a user based on light received by the light receiving unit or light receiving units.
