==Original Abstract Submitted==

A system include a light source configured to emit quasi-coherent light to tissue of a patient, the light source configured to emit the quasi-coherent light through at least one of a nasal passage or an ear canal of the patient. The system includes a detector configured to detect resulting light passing through at least a portion of the tissue and generate an interference pattern image. The interference pattern image is representative of the portion of the tissue interacting with the quasi-coherent light traveling through the nasal passage or the ear canal of the patient. The system includes processing circuitry configured to receive the interference pattern image from the detector, generate a speckle contrast signal based on the interference pattern image, determine, based on the speckle contrast signal or a metric derived therefrom, a physiological characteristic of the patient, and output a representation of the physiological characteristic of the patient.
