US 2019/0290120 A1 · APPARATUS AND METHOD FOR MEASURING PHYSIOLOGICAL PARAMETERS OF EYE

Abstract

An apparatus and a method for measuring physiological parameters of an eye. The apparatus includes a transmitter for transmitting a first set of electromagnetic waves of a first set of frequencies towards the eye, a receiver for receiving reflected electromagnetic waves corresponding to the transmitted first set of electromagnetic waves of the first set of frequencies, a comparator configured to compare the transmitted first set of electromagnetic waves with the received reflected electromagnetic waves for determining an amplitude response and a phase response for each of the electromagnetic waves of the first set of frequencies, and a calculation unit configured to fit the determined amplitude response and phase response to a physiological model of the eye to determine the physiological parameters of the eye.
