<P>PROBLEM TO BE SOLVED: To provide a biological authentication apparatus which prevents forgery for realizing precise identification by easily focusing on fingerprint and a blood vessel pattern of veins by a simple constitution for imaging clearly. <P>SOLUTION: The biological authentication apparatus 100 has a transparent plate 110 formed of a glass or a plastic for placing an object OBJ being a finger of a person to be identified facing down in the figure (with a surface having the finger print facing down), an illuminator 120 for photographing the finger print, an illuminator 130 for photographing the veins, and an imaging device 140. The imaging device 140 is provided with an imaging lens apparatus 200 for imaging an object disperse image having passed through an optical system and a phase plate, an image processor 300 for generating a dispersion-free image signal from a dispersed image signal from the imaging element 220, and an irradiation wavelength detector 400 for generating irradiating wavelength information. The image processor 300 generates the dispersion-free image signal from the dispersed image signal based on the information generated by the irradiation wavelength detector 400. <P>COPYRIGHT: (C)2008,JPO&INPIT |
