Although contemporary, contact methods of measuring cardiovascular health are accurate and applicable, a noncontact
optical sensor that detects these same parameters of health and eliminates the inconvenience of patient
contact would be useful to the medical community. Techniques of mapping and imaging blood flow with laser
speckle contrast imaging have shown promise as a non-contact health sensor. This paper explores using a laser
speckle detector to detect blood pressure, pulse pressure waves, and pulse wave velocity at a standoff. The laser
speckle detector was able to detect pulse pressure waves and with further development, may be able to measure
pulse wave velocity and blood pressure.
