More Information
Summary:An optical sensor that captures a heart rate and/or a blood oxygen content includes a light source including a light emittor that emits electromagnetic radiation with a first wavelength range including green light, a second wavelength range including red light and a third wave-length range including infrared radiation, and three light detectors, each including a filter for electromagnetic radiation, wherein a first filter is transmissive for light of the first wavelength range and non-transmissive for light of the second wavelength range and the infrared radiation of the third wavelength range, a second filter is transmissive for light of the second wavelength range and non-transmissive for light of the first wavelength range and the infrared radiation of the third wavelength range and a third filter is transmissive for the infrared radiation of the third wavelength range and non-transmissive for light of the first and the second wavelength range.
