Abstract: A pulse oximetry device includes a light emission device configured to emit light with a wavelength in a first wavelength interval and light with a wavelength in a second wavelength interval, a first light detector configured to detect light with a wavelength in the first wavelength interval, but not to respond to light with a wavelength in the second wavelength interval, and a second light detector configured to detect light with a wavelength in the first wavelength interval and detect light with a wavelength in the second wavelength interval, wherein the first light detector has a first light reception surface, the second light detector has a second light reception surface, and the first light reception surface and the second light reception surface are arranged in a common plane and are interleaved with one another.
