Non-contact reflection photoplethysmography (NRPPG) is being developed to trace pulse features for comparison with
contact photoplethysmography (CPPG). Simultaneous recordings of CPPG and NRPPG signals from 22 healthy subjects
were studied. The power spectrum of PPG signals were analysed and compared between NRPPG and CPPG. The
recurrence plot (RP) was used as a graphical tool to visualize the time dependent behaviour of the dynamics of the pulse
signals. The agreement between NRPPG and CPPG for physiological monitoring, i.e. HRV parameters, was determined
by means of the Bland-Altman plot and Pearson’s correlation coefficient. The results indicated that NRPPG could be
used for the assessment of cardio-physiological signals.
