System and method of capturing and producing biometric-matching quality fingerprints and other types of dactylographic images with a mobile device
First Claim
1. A non-powered optical module arranged to acquire a dactylographic image comprising:
- an attachment mechanism adapted to affix the optical module to a location proximate to a camera lens of a camera of a smartphone;
a housing having a side with an aperture formed therein, and a window framing a transparent surface arranged to contact a skin surface of a person;
a lighting mechanism arranged to provide light to illuminate the skin surface of the person when placed upon the transparent surface;
a prism having;
a first side facing the lighting mechanism,a second side facing the window, anda third side through which a dactylographic image of the skin surface of the person exits the prism; and
a plurality of light reflecting surfaces within the housing spatially separated from the prism, the plurality of light reflecting surfaces disposed within the housing to reflect the dactylographic image of the skin surface of the person exiting the prism towards the aperture in the side of the housing toward lens of the camera.

Abstract
An optical module includes a housing with a lighting mechanism, an aperture formed therein, and a window that frames a transparent surface adapted to contact a skin surface of a person, for example, a fingertip. The lighting mechanism provides light to illuminate the skin surface placed upon the transparent surface. A prism has a first side facing the lighting mechanism, a second side at the window, and a third side through which a dactylographic image exits the prism. One or more light reflecting surfaces are disposed within the housing to reflect the dactylographic image towards the housing aperture. The optical module is coupled to a mobile device having a camera, with the aperture of the housing aligning with a lens of the camera. The camera acquires the dactylographic image, and the mobile device adjusts this dactylographic image to produce a dactylographic image suitable for biometric matching.

11. A non-powered optical module to assist with capturing a dactylographic image from a person, comprising:
-
a frame portion adapted to mechanically couple the optical module to a smartphone, the optical module having a diffuser window arranged to diffuse ambient light, the frame portion having an aperture, and a second window arranged to contact a skin surface of the person, the frame portion coupling the optical module to a camera of the smartphone such that the aperture of the frame portion aligns with a first lens of the camera of the smartphone; a prism disposed in the frame portion with a first side of the prism facing the second window and a second side of the prism facing the diffuser window, diffused ambient light entering the optical module through the diffuser window and illuminating the skin surface; and a second lens arranged to focus the dactylographic image of the skin surface exiting the prism and propagating towards the aperture. - View Dependent Claims (12, 13, 14, 15)
