Abstract: A vital sensor includes at least one pixelated emitter array with first and second pixels. The pixels are configured to emit light of a wavelength range in the direction of a projection surface. The vital sensor also includes an optical element, arranged between the at least one pixelated emitter array and the projection surface, and which is configured to direct light of the first pixel onto a first region of the projection surface and light of the second pixel onto a second region of the projection surface which differs from the first region. The vital sensor further includes a photodetector configured to detect the light emitted by the pixels and reflected on the projection surface. The vital sensor additionally includes an evaluation unit configured to control the first pixel and the at least one second pixel in a pulsed and time-sequential manner to determine a first reference value.

Abstract: An optoelectronic biosensor includes a housing with a transparent support surface. The optoelectronic biosensor also includes an emitter device in a first region of the housing adapted to generate and emit light toward the support surface. The optoelectronic biosensor further includes a detector device in a second region of the housing. The optoelectronic biosensor additionally includes a first optical fiber element between the detector device and the support surface. The first optical fiber element is configured to guide light incident on the support surface at an angle less than a predetermined angle to a normal to the detector device. The predetermined angle depends at least on a difference in refractive indices at an interface between the optical fiber element and a material surrounding the optical light guide element. A material of the first region surrounding the emitter device is the same as the material surrounding the first optical fiber element.
