An optokinetic drum capable of providing moving visual stimuli from 6 degsec to 120 degsec has been constructed. The main drive is provided by a Vickers hydraulic transmission. Control of drum velocity varies from an error of 15 at 2 RPM to .7 at velocities of 6 RPM and above. In addition, it is possible to accelerate the device on a linear ramp quite accurately. The device provides a wide choice of stimulus presentations and can be used for a number of experiments related to oculomotor function. Author
