Abstract

Se compone de un sistema de iluminación a base de LED''s y una placa difusora 1, un prisma captador 2 que posee una fina película de adhesivo acrílico y un juego de espejos 3,4,5 que sirven para transmitir la imagen de la huella hacia el objetivo 6, tras el cual hay un dispositivo electrónico de lectura 7 donde se crea la imagen con inversión lateral. Una adecuada inclinación del dispositivo electrónico de lectura, evita la pérdida de calidad en los extremos de la huella. Una carcasa ergonómica a base de fundición de aluminio con un peso significativo y patas adherentes hace que el lector no deslice. Está diseñado para ser utilizado como componente de un sistema de control biométrico que transmite la señal vídeo a un ordenador (PC) que posee una tarjeta digitalizadora y a su vez tiene acceso a unas librerías de huellas.
