Abstract

The vector voltmeter gives on line both phase and amplitude of the ERG (electroretinogram) response to a flickering stimulus. This makes the apparatus useful in determining spectral sensitivity functions and dark adaptation curves of man and animals, in particular since it enables automatic measurement of these functions. The limitations and applications are briefly discussed.
