Pulse Sensor for Detecting the Pulse of a Living Organism

A pulse sensor comprising:

• 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 comprising 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, the converted light being modulated in a manner corresponding to the modulated scattered light, 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.
