Elaborated the definition of electrooculogram and the mechanism of canthus detection of eyeball slewing.The homopolar lead mode and the bipolar lead mode of EOG were introduced by the voltage characteristic of the reference electrode on the counterpart-electrodes and the characteristics of the bioelectricity differential amplifier.The theory of two different lead mode were further demonstrated by the comparison of the waveform of their experiment data. Then,the lead modes of EOG was clear.Both the two lead modes have their advantages and drawbacks and they are correlative with each other.In this paper,for different purposes of EOG testing provided the lead modes on the basis of the theory.
