OPTICAL DEVICE FOR MEASURING A HEART RATE OF A USER |
| 摘要 |
The invention relates to an optical device for measuring a heart rate of a user. Said optical device comprises: two light sources (1,2) for emitting light into the skin of the user, a sensor (3) for sensing the light signals emitted by each of the two light sources and reflected through the skin of the user so as to determine the heart rate of the user. The two light sources (1,2) are situated at different distances from the sensor such that the light signals received from each of the two light sources have a different penetration depth into the skin. |

1. Optical device for measuring a heart rate of a user, said device comprising:
two light sources for emitting light into the skin of the user, a sensor for receiving light signals from the light emitted by each of the two light sources and reflected through the skin of the user so as to determine the heart rate of the user, wherein the two light sources are situated at different distances from the sensor such that the light signals received from each of the two light sources have a different penetration depth into the skin.
wherein the device further comprises a temperature sensor for measuring an ambient temperature and a control unit which is configured to select the light source Which is farthest from the sensor when the ambient temperature measured by the temperature sensor is below a predetermined threshold. |
