摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine and medical equipment and is intended for increasing accuracy of determination of human visual system persistence. Tested person is shown pairs of light pulses, standard, 80 ms long, and regulated in duration, repeated after time interval, T, equal 1 s. At the first stage of measurements time of delay or early termination of regulated in duration pulse with respect to the standard one is increased discretely with 5 ms long step, until tested person determines the moment of subjective sensation that light pulses do start or finish not simultaneously. At the second stage of measurements time of delay or early termination of regulated in duration pulse is decreased discretely with 3 ms long step, until tested person determines the moment of subjective sensation that light pulses start or finish simultaneously. At the third stage of measurements time of delay or early termination of regulated in duration pulse is increased discretely with 1 ms long step, until tested person determines the moment of subjective sensation that light pulses do start or finish not simultaneously. Time of demonstration delay or time of early termination of regulated in duration pulse relative to time of standard pulse demonstration, determined at the last stage, is fixed and taken equal to time of human visual system persistence, which is marked on the plane in coordinates "time of persistence - number of measurement". Described procedure is repeated, graph showing dependence of values of human visual system persistence time tpers is built as function tpers =f(Ni), where Ni is number of i-th measurement, i=1, 2,…, k, k is quantity of measurements until obtaining quasistationary mode, when transition process is over. In quasistationary mode set quantity of measurements are made, after which value of time of human visual system persistence is calculated as arithmetic mean by formula: where tpers j is value of time of human visual system
