Abstract
A pulse waveform measurement system includes an LED light source providing an incident beam having a predetermined wavelength onto a radial or other artery, samples reflected light at a predetermined sample rate, computes, and displays a pulse waveform and various parameters associated therewith. The wavelength and sample rate are set so as to provide desired data quality.
