Abstract
According to an aspect, a detection device includes: a first optical sensor configured to detect light; a second optical sensor provided adjacent to the first optical sensor and configured to detect light; a first light source configured to emit light having a predetermined wavelength; a second light source configured to emit light having a wavelength different from that of the light emitted by the first light source; a controller configured to cause the first light source and the second light source to simultaneously emit the light; and a signal processor configured to perform processing to obtain a blood oxygen saturation level based on a value detected by the first optical sensor and a value detected by the second optical sensor. The first optical sensor and the second optical sensor are configured to detect light that has been reflected in a living body or transmitted through the living body.
