Abstract

OBJETO DE LA PRESENTE INVENCION ES UN PROCEDIMIENTO Y UN DISPOSITIVO PARA MEDIR DISTANCIAS ENTRE UN OBJETO Y UN PUNTO DE REFERENCIA. EL OBJETO SE IRRADIA POR MEDIO DE UNA RADIACION ELECTROMAGNETICA, A PARTIR DE UNA FUENTE DE RADIACION EN UN PUNTO LUMINOSO, Y LA IRRADIACION EMERGENTE DEL PUNTO LUMINOSO SE CAPTA POR UN CABEZAL DE MEDICION, Y A PARTIR DE ELLO SE DETERMINA LA DISTANCIA ENTRE EL OBJETO Y EL PUNTO DE REFERENCIA. SEGUN LA INVENCION, EL OBJETO ES EXCITADO EN EL PUNTO LUMINOSO POR LA IRRADIACION ELECTROMAGNETICA PARA LA EMISION DE UNA RADIACION INCOHERENTE ESPACIAL, Y PARA LA DETERMINACION DE LA DISTANCIA SE UTILIZA TAN SOLO SELECTIVAMENTE LA PARTE INCOHERENTE ESPACIAL DE LA RADIACION EMITIDA Y EXCITADA EN EL PUNTO LUMINOSO.
