Abstract
An electronic device, comprising: a first light source, configured to emit first light; a second light source, configured to emit second light; a first optical sensor, configured to sense first optical data generated based on reflected light of the first light; a light guiding device, configured to receive the second light; and a second optical sensor, configured to sense second optical data generated based on the second light emitted by the light guiding device. The first optical sensor and the second optical sensor can be integrated to a single optical sensor.
Claims18
An electronic device, comprising:
- a first light source, configured to emit first light;
- an optical component, configured to receive the first light from the first light source, and configured to pass partial of the first light;
- a second light source, configured to emit second light;
- a first optical sensor, configured to sense first optical data generated based on reflected light of the first light, wherein the reflected light of the first light is reflected by the optical component and transmitted to the first optical sensor;
- a light guiding device, configured to receive the second light;
- and
- a second optical sensor, configured to sense second optical data generated based on the second light emitted by the light guiding device.
An electronic device, comprising:
- a first light source, configured to emit first light;
- an optical component, configured to receive the first light from the first light source, and configured to pass partial of the first light;
- at least one second light source, configured to emit second light;
- a light guiding device, configured to receive the second light;
- and
- an optical sensor, configured to sense first optical data generated based on reflected light of the first light, and configured to sense second optical data generated based on the second light emitted by the light guiding device;
- wherein the reflected light of the first light is reflected by the optical component and transmitted to the optical sensor.
