    Abstract: A process for reproducing hand and/or finger lines with a camera works without skin contact with the recording device. By using linearly or circularly polarized light in the paths of the illuminating and the reproducing light rays, it is possible to obtain separate representations of the patterns of the epidermis and the hypodermis. An image of the relief of the skin that is rich in contrast is obtained in this way, and it is possible to acquire information from the deeper disposed layers of the skin already supplied with blood. An algorithm searches the skin patterns of the palm of the hand for line elements of different strengths and directions (vectors). The computed numerical identification contains overall frequencies of vectors as well as amplitudes and phases of frequency components of projections of the vector image of both patterns. The process permits placing the person to be identified in a separate location from the measuring device, thereby offering complete protection of the system and enhanced security against fraud.

    Abstract: La invencion se refiere a un metodo para representar imagenes de la mano y/o lineas del dedo con una camara que funciona sin hacer contacto con la piel con el dispositivo de grabacion. Utilizando una luz polarizada circular o lineal en la trayectoria del haz representadora de imagen y de iluminacion, se hace posible una representacion separada del patron de piel inferior y superior. Al hacer esto, se obtiene una imagen del relieve de la piel que es rico en contraste. Ademas, puede obtenerse la informacion con respecto a las capas de la piel que yacen mas profundas a traves de la cual la sangre fluye. Un algoritmo explora el patron de la piel de la superficie de la mano por elementos lineales de diferentes espesores y direcciones (vectores). La identificacion numerica calculada contiene las frecuencias totales de los vectores, amplitudes y fases ocurrentes de componentes armonicos de proyecciones de imagenes de vector de ambos patrones. El metodo hace posible identificar personas a distancia, proteger completamente el dispositivo de medicion y proporcionar una seguridad mejorada contra engano.
