According to an aspect of the invention there is provided a portable pulse measuring device. The device comprises a lighting configuration comprising at least three elements (100, 102, 104, 106) selected from a light-emitting source (104, 106) for emitting radiant energy through a human body tissue and a light detector (100, 102) for detecting the intensity of said radiant energy after propagation through the human body tissue and for providing input signals representative of said propagation, wherein the lighting configuration comprises at least one light-emitting source (104, 106) and at least one light detector (100, 102); processing means for determining pulse rate in response to processing the input signals. The elements in the lighting configuration are arranged in the portable pulse measuring device in a configuration where the light-emitting sources (104, 106) in the lighting configuration are asymmetrically disposed in relation to the light detectors (100, 102) in the lighting configuration. |
