Abstract

EL APARATO SE UTILIZA PARA LA MEDICION DE LA CURVATURA DE UNA SUPERFICIE (4). ESTE CONSTA DE AL MENOS UNA FUENTE DE RADIACION ELECTROMAGNETICA (1), UN MECANISMO DETECTOR DE RADIACION ELECTROMAGNETICA (6) Y UN MECANISMO DE LENTES (7) POSICIONADO Y COLOCADO PARA ENFOCAR LA RADIACION DE FUENTE REFLEJADA DE DICHA SUPERFICIE (4) SOBRE DICHO MECANISMO DETECTOR (6). UN DIVISOR DE HAZ (5) SE ENCUENTRA POSICIONADO ENTRE DICHO MECANISMO DETECTOR (6) Y LA SUPERFICIE (4) MEDIANTE EL CUAL LA RADIACION DE DICHA FUENTE (1) ES DIRIGIDA SOBRE LA SUPERFICIE. SE PROPORCIONA UN MECANISMO DE CALCULO PARA CALCULAR DICHA MEDICION DESDE LAS SEÑALES DETECTADAS POR DICHO MECANISMO DETECTOR (6). EL MECANISMO DETECTOR ES BIDIMENSIONAL, Y UN MECANISMO DE ESCANEO (26) SE PROPORCIONA QUE PROVOCA QUE SE ESCANEE UN HAZ DE RADIACION DE DICHA FUENTE A TRAVES DE LA SUPERFICIE (4), PRODUCIENDO ASI UNA MULTIPLICIDAD DE HACES QUE SE REFLEJAN DESDE DICHA SUPERFICIE A TRAVES DE DICHO MECANISMO DE LENTES (7), DONDE UN ANGULO REFLEJADO DE DICHO HAZ SE TRANSFORMA EN UN DESPLAZAMIENTO FISICO SOBRE DICHO MECANISMO DETECTOR (6). EL MECANISMO DE ESCANEO (26) PUEDE SER UN PRISMA DE ESPEJO PARA TAL FIN O UNA GUILLOTINA DE LUZ UTILIZADA EN COMBINACION CON OTRO MECANISMO DE LENTES.
