ABSTRACT:
In order to obtain a clear surface pattern of an object such as a fingerprint impression and the like, a surface of an optical element against which the object is impressed is made of an elastic and/or viscous material. Thus, a surface pattern with high contrast is available even if the surface to be imaged is dry.
