Abstract: A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.

Abstract translation: 公开了一种光电体积描记术（PPG）装置。 PPG装置可以包括一个或多个光发射器和一个或多个光传感器，以产生用于测量用户的PPG信号和灌注指数的多个光路。 每对光发射器和光检测器之间的多个光路可以包括不同的间隔距离，以产生精确的PPG信号和灌注指数值，以适应各种用户和使用条件。 在一些示例中，由于例如由设备的倾斜和/或拉动，用户的头发，用户的皮肤色素沉着和/或运动引起的伪影，多个光路可以包括用于噪声消除的相同的分离距离。 PPG装置还可以包括一个或多个透镜和/或反射器，以增加信号强度和/或使遮蔽光学部件和相关联的布线不被用户可见。
