Abstract
An integrated spectrum sensing device for real-finger judgement includes a fingerprint sensing array, an optical unit and a signal processing unit. The fingerprint sensing array optically coupled to the optical unit includes multiple spectrum detecting units receiving light from a finger through the optical unit to detect spectrum distributions or variations outputted from the finger to obtain multiple sets of heterogeneous spectrum data. The signal processing unit electrically coupled to the spectrum detecting units performs measurement domain analysis according to the sets of heterogeneous spectrum data to judge whether the finger is real. A sensing method is also disclosed.
