Abstract:
Methods and system for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The gaze direction of the eye of the subject is determined and an interrogation signal source and/or response signal sensor are moved into alignment with the eye using an actuator to facilitate detection of the signal from the eye of the subject.
