Abstract
The study presents measurement and numerical analysis of time variability of the eye pupil geometry and its position, as well as their correlations with blood pulsation. The image of the eye pupil was recorded by use of the fast CCD camera with 200 fps rates. Blood pulsation was synchronously recorded by use of pulse transducer with the sampling frequency of 200 Hz. Each single image from a sequence was numerically processed. Contour of the eye pupil was approximated, and its selected geometrical parameters as well as center positions were calculated. Spectral and coherence analysis of time variability of calculated pupil parameters and blood pulsation were determined.
