Abstract
An imaging device may have illumination paths directed to an imaging area to thereby illuminate the whole of the imaging surface. The imaging area may be adapted to generate frustrated total internal reflection of the illumination from the imaging surface, in the presence of an element in contact with some or all of the imaging surface.
