METHOD FOR ESTIMATING HUMAN VISUAL SYSTEM RESPONSE TIME Russian patent published in 2008 - IPC A61B3/00 A61B5/16 

FIELD: medicine.

SUBSTANCE: method allows for determining response time of human visual system by presenting sequences of paired light pulses of set duration separated by inter-pulse interval repeated in constant time interval. With duration of light pulses equalling 50 msec, duration of inter-pulse interval between light pulses in pair is reduced, until tested person determines moment of subjective fusion of two light pulses in pair into one. Duration of inter-pulse interval between light pulses in pair in this moment is taken for its first threshold value t_thr1. Further on, with duration of light pulses being 200msec, duration of inter-pulse interval between light pulses in pair is reduced, until tested person determines moment of subjective fusion of two light pulses in pair in one. Duration of inter-pulse interval between light pulses in pair at this moment of time is taken for its second threshold value t_thr2. Response time is taken equal to sum of duration of threshold inter-pulse interval t_thr1 with duration 50 msec and duration of threshold inter-pulse interval t_thr2 with duration 200 msec.

EFFECT: increased accuracy of determining time of recovery of human visual system.
