A new laser interferometer for the stimulation of pattern-reversal visual evoked potentials.
A laser interferometer for visual-evoked-potential (VEP) stimulation that allows a rapid pattern reversal in less than 0.5 ms and a continuous variation of the spatial frequency of the pattern is described. The interferometer is applied for the assessment of objective visual acuity. The Fourier transform of the VEP response to the rapid pattern reversal shows an extremely small bandwidth.
