Paper Abstract

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.
