DESCRIPTION OF OPTOKINETIC DEVICE.
Abstract
An optokinetic drum capable of providing moving visual stimuli from 6 deg/sec to 120 deg/sec 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)
