Abstract
The invention relates to a physiological property determination apparatus () for determining a physiological property like a pulse rate of a person. The apparatus may be configured to be worn on the wrist like a watch. A controller () separately controls at least two light sources () for emitting at least two light beams having different wavelengths into tissue of the person and a light detector () having a two-dimensional detection surface () detects light, which has travelled through the tissue, wavelength-dependently and generates a wavelength-dependent two-dimensional image based on the detected light. Based on the generated wavelength-dependent two-dimensional image the physiological property is determined. The separate control of the light sources allows for an independent optimization of the illumination and detection processes for each wavelength, which in turn can lead to an improved determination of the physiological property based on the wavelength-dependent two-dimensional image.
