Method of measuring a physiological parameter of an organism, measurement system and physiology monitoring device

摘要

The present invention is directed at a method of and system for measuring a parameter of a body, in particular a physiologic parameter of an organism, such as a human or animal body, or a concentration of a substance in a contained volume. The method is performed using a measurement system comprising an illumination unit and a sensor unit. The method comprising illuminating a body part of the body by providing electromagnetic radiation to an illumination area on the body part using the illumination unit, receiving by the sensor unit at least part of said radiation which has travelled via the body part, and analysing by a processing unit an output signal from the sensor unit using an analysis algorithm for determining a measurement value of said physiological parameter. Illumination of the body part is performed by emitting the radiation from a planar radiation emitting surface of the illumination unit for providing the radiation comprising a substantially planar homogeneous wave front in at least a part of the illumination area.
