Abstract
An apparatus and a method for detecting bio-information are provided. The apparatus includes a bio-signal detector including a light emitter including a light-emitting diode (LED) and a laser diode (LD), the LED and the LD being configured to emit optical signals on an object. The bio-signal detector further includes an optical detector including a light-receiver configured to detect optical signals modulated by the object. The apparatus further includes a processor configured to process the optical signals to detect the bio-information of the object.

12. A method of detecting bio-information, the method comprising:
-
driving a plurality of light-emitting diodes (LEDs) and a plurality of laser diodes (LDs) with a delay time to irradiate lights having different divergent angles on an object with the delay time, the plurality of LEDs and the plurality of LDs being disposed in a two-dimensional array; detecting signals that are reflected and modulated by the object, the signals having the delay time, and the signals being detected by an optical detector comprising a plurality of light-receivers disposed to surround the plurality of LEDs and the plurality of LDs; and selecting, by a processor, a signal having a signal-to-noise ratio greater than a value from the signals that are detected, or combining the signals that are detected, to detect the bio-information of the object. - View Dependent Claims (13, 14, 15)
