Abstract

An improved apparatus and method for obtaining images through a prism are provided. In an embodiment, a thin fingerprint prism wedge, with a geometry designed to minimize foreshortening and maximize contrast, is provided in an optical path between an optical sensor and an object to be imaged. In some embodiments, the apparatus operates on the principle of internal surface reflections instead of total internal reflection (TIR).
