DEVICE FOR OBTAINING IMAGE OF TWO IRISES WITH ONE IMAGING DEVICE

摘要

PURPOSE: A device for obtaining an image of two irises with one imaging device is provided to reduce wrong recognition without an extra expense by obtaining the image of two irises through one imaging device. CONSTITUTION: The first and the second object lens(210a,210b) receive the iris images through the first and the second optical path. The first/second/third full reflection glasses(250a,250b,250c) reflect the iris image inputted through the object lenses to a direction to a beam splitter(240). As a glass(240) comprising an upper half of the full reflection glass and a lower half of the penetration glass is diagonally arranged, the beam splitter combines the two iris images by passing the iris image of the first optical path and reflecting the iris image of the second optical path. A CCD(Charge Coupled Device) camera(260) pictures the images of the first and the second optical path passing an image collecting device(200).
