Abstract
A photoelectron fingerprint identifying apparatus is disclosed. The disclosed photoelectron fingerprint identifying apparatus may include a photoelectron sensor having a light receiving surface on which a finger is placed, wherein the photoelectron sensor receives an optical intensity signal associated with an invisible light penetrating the finger before converting the optical intensity signal to a photocurrent signal, an analog/digital converter electrically coupled to the photoelectron sensor for receiving the photocurrent signal, wherein the analog/digital converter converts the photocurrent signal to a digital signal, and an image processing unit electrically coupled to the analog/digital converter for receiving the digital signal before outputting an fingerprint pattern based on the digital signal.
