Abstract

EL PROCESO Y EL DISPOSITIVO PERMITEN PARTICULARMENTE MEDIR EL DESPLAZAMIENTO Y LA VELOCIDAD DE UN VEHICULO SOBRE UNA VIA. SE FORMA, A PARTIR DE UN PRIMER COMPONENTE DE LOS COMPONENTES MOVILES UNO RESPECTO DE OTRO, DOS IMAGENES SUCESIVAS DE LA RED DE INTERFERENCIA OBTENIDAS POR ILUMINACION CON UNA LUZ COHERENTE, A PARTIR DEL PRIMER COMPONENTE, DEL SEGUNDO COMPONENTE (10) CON UN CAMPO SUFICIENTEMENTE EXTENDIDO PARA QUE UNA PARTE COMUN DEL SEGUNDO COMPONENTE PARTICIPE EN LA FORMACION DE LAS DOS IMAGENES DE L RED DE INTERFERENCIA Y SE DETERMINA EL MAXIMO DE LA FUNCION DE INTERCORRELACION ESPACIAL ENTRE LAS DOS IMAGENES, CARACTERIZADO EN QUE SE FORMAN LAS DOS IMAGENES POR DOS ILUMINACIONES SUCESIVAS BREVES, QUE TIENEN SENSIBLEMENTE LA MISMA INCIDENCIA, DECALADAS RESPECTO DEL PRIMER COMPONENTE POR UNA DISTANCIA CORRESPONDIENTE APROXIMADAMENTE AL DESPLAZAMIENTO RELATIVO INTERVENIDO ENTRE LOS COMPONENTES.
