Abstract:
1. A device comprising: an imaging tray having a bottom and a sidewall forming an interior surface including a fluorescent surface of known dimensions that fluoresces over a range of wavelengths including a first wavelength of light and a second wavelength of light; a medium disposed within the interior surface, the medium capable of yielding to form an impression of an object inserted into the imaging tray, wherein the medium absorbs the first wavelength of light more than a second wavelength of light; a light source for illuminating the medium; a camera adapted to capture one or more images of the medium at the first wavelength and the second wavelength; and a processor programmed to use the one or more images, in view of the known dimensions of the interior surface, to determine a shape of the object based upon a ratio of an intensity of the first wavelength and an intensity of the second wavelength in one or more directions.
