Measurement of the Impulse Response of the Human Visual System Using Correlation Techniques

Abstract

This thesis applies random signal testing techniques to the human visual system. A binary maximal length sequence was used to modulate a fluorescent light bank by about 15%. With this pseudo-random noise as a visual input, subjects were monitored with an electroencephalograph (EEG). The cross- correlation between the pseudo-random input and the EEG output yields an estimate of the subject's visual system impulse response. An attempt was made to verify the impulse response using matched filter theory. Keywords: Data acquisition. (KR)
