AN OPTICAL FINGERPRINT SCANNER The present invention relates to an optical fingerprint scanner (3) optics for coherent gating liveness detection involving a second prism to form Zero path difference Michelson interferometer, which forms the image of internal finger surface with the concept of coherent gating image...

An optical illumination system comprises discrete light sources, collimating lens, lens array, an imaging optical module, and a detector. The light sources are supported by the collimating lens to generate discrete angular beams that produce an irradiance pattern via the lens array. The lens array produces the irrad...
