摘要：
An optical sensor and a method of using the optical sensor in an optical measuring device that measures cardiovascular properties and compensates for movement artifacts by directing a sheet of light towards an artery. The optical sensor may include one or more light sources, one or more transmit light guides coupled to the one or more light sources and configured to direct light from the one or more light sources as a sheet of light towards an artery, such that the cross-sectional profile of the sheet of light may have a length transverse to a longitudinal direction of the artery that is longer than the diameter of the artery. The optical sensor may include one or more light detectors configured to receive backscattered light and generate an output based on the received backscattered light that is a reflection of the sheet of light from the artery and surrounding tissues.
