ABSTRACT:
Disclosed is an apparatus for forming a high contrast image of a patterned object, such as a fingerprint, including a first lens having a light receiving surface and a viewing surface and a second lens adjacent to the viewing surface of the first lens. A light source projects incident light into the first lens between the viewing surface and imaging surface such that at least a portion of the incident light undergoes total internal reflection. In this way, an image of the patterned object is generated by substantially all scattered light from the imaging surface.
