Instrumentation for Automated Study of Human Pupil Responses

Instrumentation has been developed for studying the responses of the human pupil to different kinds of visual stimuli. This involves stimulating the eye visually, acquiring pupillary diameter data samples, analyzing them, and displaying and storing the results All of these functions are controlled by a minicomputer. The apparatus is a convenient research tool for studying the visual system of color-normals and color-defectives by observing pupillary behavior.
