The image-based system is used to observe and document eye responses which can be used to implement the procedures defined in the Standardized Field Sobriety Test as well as the Drug Recognition Expert Program. These eye responses include pupil movement as well as pupil size and responses, for either one or both eyes simultaneously. The system includes a headset against which the subject places their face. The faceplate has two eye openings through which illumination devices transmit beams of infrared light to illuminate the subject's eyes. Two imaging devices are mounted on the headset opposite the eye openings to generate images of the subject's illuminated eyes. The generated images are transmitted to an image recording device for storage and an image display device for display to a test administrator.
