Abstract
The principles of impedance calibration are presented. The method of transpalpebral rheoophtalmography is briefly discussed. The paper presents hardware and software for the impedance calibration before the registration of rheographic signals. Calculations made in analyzing signals are presented, which show that the errors contribution to the total volume of registered signal is significant. The algorithmic solution of the rheograph calibration is proposed. Results of the calibration are shown with specific two-channel rheograph.
