APPARATUS FOR FILMING OCULAR IRIS

摘要

PURPOSE: An apparatus for filming an ocular iris is provided to enable an operator to film the iris on the whole by expanding an upper eyelid and a lower eyelid together for a specific time, and to clearly film the iris by eliminating the generation of reflected rays on the iris. CONSTITUTION: The apparatus for filming an ocular iris consists of an upper/lower eyelid expanding part(300), a proximal shot lens part(240), an iris lighting part(500), a zoom lens part(220), and a CCD(charge coupled device) open phase part(210). The upper/lower eyelid expanding part expands the upper/lower eyelids according to the detecting action of a proximal optical sensor when an eyeball of a patient contacts with upper/lower tip ends of a body(110) with a handle(120). The proximal shot lens part is disposed in the body between the upper eyelid and the lower eyelid. The iris lighting part is located at right and left sides of the iris to emit light around the iris. The zoom lens part is installed on the rear side of the proximal shot lens part to adjust a focus distance between the lens part and the iris. The CCD open phase part process the images of the iris by receiving the images from the proximal shot lens part.
