  • Fingerprint acquisition assembly using prism and camera
    Publication number: 20020146157
    Abstract: A fingerprint acquisition assembly (110) includes a camera (205) for capturing an electronic image at a first focal range. An optical interface such as prism (207) or lens and mirror assembly (501,503) is used to provide a macro image to the camera (205) at a second focal range.
