Optical speed and distance sensors were first introduced into the arena of vehicle dynamics testing in 1981. They have developed significantly since that time and are now used in Formula 1 and throughout the automotive industry for distance measuring in all manner of operating states like standstill, braking, high-speed ride navigation and positioning, measuring the slip-free acquisition of vehicle speed, the determination of slip between rail and track wheel, and the acquisition of speed changes with direct reference to the track. CORRSYS-DATRON has been at the forefront of this development over the period and has worked continually to bring increasingly higher levels of accuracy and repeatability to the measurement of dynamic variables including speed, distance, angle and height.
