Abstract:
An imaging device may have an imaging surface and a sensor. The imaging surface may be illuminated by a first source and reflect at least some of the illumination to the sensor to detect an image. The imaging device may have a predetermined width and an optical path passing therethrough. The imaging device may be illuminated by a second source, and the illumination of the second source may be directed to one or more predetermined regions on or near the imaging surface to produce an optical effect associated with the imaging surface.
