Patent ID: 7550707

Claim:
A biometrics authentication system comprising: a light source applying light to a living organism; a microlens array section condensing light from the living organism, and including a plurality of microlenses each having a different refractive power; an image pickup device obtaining image pickup data on a plurality of layers of the living organism on the basis of the light condensed by the microlens array section; and an authentication section performing authentication of the living organism on the basis of the image pickup data on the plurality of layers of the living organism; and a voltage supplying section supplying a voltage to the microlens array section, wherein the microlenses change their refractive powers according to a voltage supplied from the voltage supplying section, and wherein the microlens array section includes: a pair of substrates; a pair of electrodes to which a voltage from the voltage supplying section is applied, the pair of electrodes being formed on the substrates; and a liquid crystal layer being arranged between the pair of electrodes, wherein at least one of the pair of electrodes has a curved surface for forming the microlenses.
