<p>Disclosed is an image capturing system including a light refractor, a light source, and a light receptor. The light refractor can be a triangular prism and includes an imaging surface against which a fingerprint or other object to be imaged is placed. The imaging surface includes at least a first layer of material which has a first part which includes a polymer and a second part which includes a fluid retained within the polymer. The fluid of the first layer can fill irregularities in the ridges of a fingerprint placed on the imaging surface. This allows a higher contrast, sharper fingerprint image to be captured. The imaging surface can also include a second layer of protective material interposed between the first layer of material and the surface of the prism to reduce breakdown or deterioration of the first layer of material due to adhesives used on the surface of the prism.</p> |
