Abstract:
A device for analyzing the surface structure of an object, the device comprising a touchable Lambertian light diffusing surface that covers a cavity containing a light source and an image sensor. The image detector senses the contact of the outer Lambertian surface of the device by a contacting object, for example a finger-tip, by means of light from the light source reflecting back to the image detector. At the same time, ambient light from objects external to the device is diffusely scattered by the Lambertian surface as it enters the cavity and does not affect the ability of the image detector to clearly determine the surface structure of the contacting object. Thus, for example, the surface contours of a fingerprint may be determined with a high signal-to-noise ratio.

Claim (Index 3):
A surface-contact method of feature analysis of an object having surface features and of comparison with similar objects, comprising the steps of:\n providing a surface contact device, wherein said device comprises a cavity within which is a light source and an image sensor sensitive to said light source and wherein said cavity is covered by a semi-transparent plate having a contactable Lambertian outer surface, wherein said semi-transparent plate is illuminated from within by said light source; contacting said Lambertian outer surface of the semi-transparent plate with an object having a surface feature to be analyzed, wherein said object is aligned against said surface in a particular position, whereby said surface feature contact said Lambertian outer surface; then illuminating said surface feature from within said cavity using said light source, whereupon said surface feature becomes visible to said image sensor as a bright reflection; while contours of images formed by ambient illumination of arbitrary intensity and frequency from background objects external to said device and not in contact with said Lambertian surface are diffusely scattered by said Lambertian outer surface and, thereby, said image sensor detects no fixed patterns from said external objects and; capturing images of said surface features while said object is in contact with said Lambertian surface for current or future analysis; then recalling from an associated memory cache a set of stored images of prepositioned similar objects created by the method described above and comparing them individually to said surface features of said prepositioned images of similar objects above.
