Abstract

Un dispositivo para detectar un tejido, el dispositivo incluye una fuente de luz adaptada para emitir luz generalmente en la direccion del tejido; unos lentes espaciados y separados de la fuente de luz y adaptados para recibir la luz que se origina desde la fuente de luz, los lentes teniendo un indice radial de refraccion; y un sensor de imagen alineado con los lentes, el sensor de imagen esta adaptado para recibir la luz de los lentes y para convertir la luz a una senal. Tambien, un metodo para detectar un tejido, el metodo incluye emitir luz desde una fuente de luz; capturar la luz reflejada por el tejido con unos lentes que tienen un indice radial de gradiente de refraccion; enfocar la luz capturada sobre un sensor de imagen; y convertir la luz enfocada en una senal. Tambien, un metodo para alinear dos tejidos, en donde cada tejido tiene una posicion y un metodo para detectar un objeto.
