NON-CONTACT FINGERPRINTING SYSTEMS WTH AFOCAL OPTICAL SYSTEMS

机译:非光学光学系统的非接触式指纹识别系统

摘要

An embodiment of a fingerprinting system may include a receiver configured to receive a finger and an image-capturing device optically coupled to the receiver and configured to capture an image of a fingerprint from a target region of the finger. The image-capturing device may include an afocal optical system. The fingerprinting system may configured so that the image-capturing device captures the image of the fingerprint from the target region without the target region of the finger being in direct physical contact with a solid surface.
