  • Publication number: 20210232798
    Abstract: A prism of an approximately quadrangle-frustum shape is arranged so that a bottom side, out of two parallel surfaces of the prism, is a placing surface side for a finger. A first imaging unit arranged below a top surface parallel to the bottom surface images an image of the finger transmitted through the top surface. A light source radiates light to at least one side surface of a first set of side surfaces, out of two sets of side surfaces of the approximately quadrangle-frustum shape that face each other. A second imaging unit images the image of the finger transmitted through a second set of side surfaces, out of the two sets of side surfaces. An infrared ray light source radiates infrared ray light into the finger so that the infrared ray light is scattered inside the finger and is received by the imaging unit.

  • Patent number: 10922523
    Abstract: A prism includes a large surface at least a portion of which is a placing region for a finger, a small surface parallel to the large surface, and first and second inclined lateral surfaces. A light source emits light to the first inclined lateral surface. A first imaging sensor arranged below the small surface receives a light transmitted from the light source through the small surface to obtain a first image. A second imaging sensor receives a light transmitted from the light source through the second inclined lateral surface to obtain a second image of which fingerprint pattern contrast is enhanced more than that of the first image. An infrared light source emits infrared ray light to the finger. The first imaging sensor receives the infrared ray light transmitted from the infrared light source through the small surface to obtain a third image for a blood vessel of the finger.

  • Patent number: 10534902
    Abstract: A prism member of an authentication apparatus includes a living body contact surface configured to be in contact with the living body, and an imaging surface opposed to the living body contact surface and formed at a position generally parallel therewith. The prism member includes a reflection surface in contact with the living body contact surface and the imaging surface, to totally reflect light reflected from the former surface toward the latter surface. The reflection surface is at angle such that (i) light through the living body contact surface into the prism member does not reach to the reflection surface, and (ii) light from an inside of the prism member is totally reflected at the living body contact surface in an optical path running from the imaging surface and reaching the living body contact surface by way of the reflection surface. A first imaging unit captures a living-body reflected light.

  • Patent number: 10521578
    Abstract: A prism member of an authentication apparatus includes a living body contact surface in contact with a visible light-radiated living body, and an imaging surface opposed to the living body contact surface and formed at a position in generally parallel therewith. The prism member includes a reflection surface in contact with the living body contact surface and the imaging surface, and to totally reflect light reflected off from the living body contact surface toward the imaging surface. The reflection surface is at an angle such that light from an inside of the prism member is totally reflected at the living body contact surface in an optical path running from the imaging surface and reaching the living body contact surface via the reflection surface. A first imaging unit captures an image including at least a part of said body contact surface and at least a part of the reflection surface.
