A system and method of positioning an eye of a subject at a selected point in space uses a holographic optical element containing indicia. The indicia are selectively visible to a user when the user is outside a volume surrounding the selected point and direct the user toward the volume. This system can be used with a camera to take an image of the eye from which the subject can be identified.
