MULTISPECTRAL OPTICAL FINGER SYSTEM FOR PHYSIOLOGICAL MEASUREMENTS

Wearable optical devices, methods and systems for obtain dynamic and static physiological parameters from a subject are disclosed. Example devices can be worn around an appendage, such as a finger, and utilize PPG sensors to obtain signals from the appendage. The PPG sensors are positioned to acquire signals suitable to reconstruct an image of the inner appendage using, for example, diffuse optical tomography, to provide additional information. The devices, methods, and systems can obtain dynamic and static physiological parameters and accurate images in real-time.
