Abstract
In an embodiment a pulse sensor includes two light sources configured to emit light in a direction of a perfused tissue of a living being so that the perfused tissue scatters the light and so that the scattered light is modulated on basis of a pulse of the living being, at least one luminescent concentrator including an entry face, an exit face smaller than the entry face, and a fluorescent material arranged in a light path between the entry face and the exit face, wherein the luminescent concentrator is configured to receive at least some of the modulated scattered light entering through the entry face, convert the entered light by the fluorescent material and emit the modulated converted light from the exit face, and one light detector configured to detect at least some of the modulated converted light emerging from the exit face, wherein, in plan view, the luminescent concentrator is strip-shaped and extends perpendicular to a connecting line between the two light sources, wherein side faces of the luminescent concentrator facing the light sources are concave, and wherein corresponding side faces extend at least partially around the light sources.
