Abstract

See full text

A compact eyeprint imaging device is provided. The device includes a plano-convex lens, a right angle triangular prism, a micro lens array, an imaging detector and an external package. The plano-convex lens and the micro lens array are glued on an inclined face of the right angle triangular prism and two right angle faces of the right angle triangular prism are coated with reflecting films, so as to form an integrated combined optical unit, which is inserted into the external package together with the imaging detector. The device is wholly installed on a glasses frame. Light emitted by the eyeprint passes through the plano-convex lens to form parallel light beams, which are reflected twice through the two right angle faces of the right angle triangular prism and then focused through the micro lens array, so as to form a multi-aperture eyeprint image array on the imaging detector.
