A method of creating a friction-ridge image is disclosed (figure 4). An energy transducer is aimed at a body part having skin (10). Th transducer is used to obtain information about the papillae beneath an outer surface of the skin. The information about the papillae is used to obtain information about valleys between the papillae (60), and a friction-ridge image having friction-ridge valleys that correspond with the valleys between the papillae is created (70). |
