Compact iris imaging system
摘要:
An iris imaging and illumination system is used to resolve and record the fine musculature features of an iris. The system can improve the quality of an iris image and facilitate the image capturing process by focusing illumination on an ocular area of a subject. By limiting illumination of other parts of a face, reflections from the face are reduced. The system has a compact physical arrangement by placing the illumination sources proximate to one another and splaying them in order to focus illumination on the ocular areas of a subject.
