Samenvatting
Considering the increase of drug influenced drivers, it becomes more and more necessary to create tests to identify drug influenced drivers. Since 1995 we have access to the compact integrated pupillograph CIP, which allows reliable measurements of pupil dynamics as well as eye movements. The principle of measurement is based on infrared reflection. The device seems to be very effective to examine effects of various psychoactive substances on brain function or vision control, respectively. The CIP is a mobile measuring device, which could also be used in the field.
