Patent ID: 7808644

Claim:
A device comprising: an opaque scattering body defining an outer side and an inner side, the scattering body having an apex; at least one camera configured and arranged to look inside the scattering body; at least one lens configured and arranged to image within the at least one camera an object which is to be examined, the object being arranged to be illuminated by the inside of the scattering body; and at least two light sources arranged to illuminate the inside of the scattering body; wherein the at least two light sources are arranged such that: illumination of the scattering body by a first of the at least two light sources continuously increases a brightness level along an intersecting line when viewed in a defined direction along a variable angle θ measured from the apex of the scattering body, the intersecting line having a starting point on a centerline of the scattering body and extending between the scattering body and an imaginary plane through the at least two light sources; and illumination of the scattering body by a second of the at least two light sources continuously decreases the brightness level along the intersecting line when viewed in the defined direction.
