Abstract: A method and system are provided for representing a structure of a kind characterized by a specific radiation response to a predetermined incident radiation. The incident radiation is applied to the structure to produce the radiation response thereof, which is detected and data indicative thereof is generated. This data is processed and analyzed to produce a predetermined output representative of a structure-related data. The output includes a non-visual portion derived from the specific radiation response of the structure and is sensory perceptible by a human being.
