ABSTRACT
A new method is described which uses photo-electric matrix method to measure two-dimensional eye movements. This system is composed of the detector unit (monitor), matrix and correction circuits and stimulus generator. A light and small detector unit attached to the modified trial frame transduces positional informations and can be achieved head-mounting. The instrument operates in the infrared, so that it does not interfere with normal vision, and over a two-dimensional visual field to +/-15 degrees. A system for generating a fixed target whose velocity, displacement, form, intensity, and other characteristics can be varied systematically also is described. The operating procedures are described and operating records are shown. Electrical and optical modifications of the present system will make possibIe the measurement of more smaller movement of the eye. Extensions and improvement of the technique of measurement are discussed briefly.
