Abstract

Um sistema biométrico pode incluir um conjunto sensor ultrassônico, um sistema de fonte de luz e um sistema de controle. Algumas implementações podem incluir um transmissor ultrassônico. O sistema de controle pode ser capaz de controlar o sistema de fonte de luz para emitir luz e receber sinais a partir do conjunto sensor ultrassônico correspondente a ondas acústicas emitidas a partir de porções de um objeto alvo em resposta a serem iluminadas com a luz emitida pelo sistema de fonte de luz. O sistema de controle pode ser capaz de realizar um processo de autenticação de usuário que é baseado, pelo menos em parte, nos sinais do conjunto sensor ultrassônico.
