US 2018/0120933 A1 · IMAGE-BASED SYSTEM, HAVING INTERCHANGEABLE VISION ELEMENTS, TO OBSERVE AND DOCUMENT EYE RESPONSES

Abstract

The image-based system is used to observe and document eye responses, which include eye gaze tracking, pupil size and reactivity, for either one or both eyes sequentially or simultaneously as well as eye lid movements, condition of the sclera, etc. that are recorded and evaluated by police officers. The system includes a faceplate against which the subject places their face. The faceplate can have illumination devices mounted thereon which transmit beams of infrared light and visual light to illuminate the subject's eyes. An imaging device is removably mounted on the frame of the image-based system to observe and document eye responses to generate images of the subject's illuminated eyes. The generated images are also transmitted to an image display device for display to a test administrator.

Dependent claims

An image-based system to enable an individual administering an impairment detection test to a subject to observe and document eye responses of the subject to applied visual stimuli, comprising:

a faceplate, removably attached to a frame, shaped to substantially conform to the subject's face when the subject places their face against the faceplate;
at least one illumination device to illuminate the subject's eyes in executing an impairment detection test when the subject places their face against the faceplate;
and
at least one imaging device, removably attached to the frame and aligned with the subject's eyes to generate an image of the subject's illuminated eyes when the subject places their face against the faceplate.

at least one imaging device, removably attached to the frame and aligned with the subject's eyes to generate an image of a subject's eyes when the subject places their face against the faceplate;
and
at least one lens, located in an image transmission path from the subject's illuminated eyes to the imaging device, for focusing the image of the subject's eyes onto optics of the imaging device;
and
at least one display device mounted on the frame and positioned in front of the individual administering the impairment detection test to display the generated images of the subject's eyes.
