Abstract

LAS PROPIEDADES OPTICAS DE UNA LENTE, INCLUYENDO LOS DEFECTOS LOCALIZADOS, SE DETERMINAN ANALIZANDO LA IMAGEN REFRACTADA PRODUCIDA POR LA TRANSMISION DE UN RAYO DE LUZ A TRAVES DE UNA ABERTURA (16) Y UNA LENTE (12) A COMPROBAR. LA IMAGEN SE REFLEJA SOBRE UNA SUPERFICIE DETECTORA SENSIBLE A LA LUZ (20). LA INFORMACION OBTENIDA DE LA SUPERFICIE DETECTORA DE LA LUZ SE DIGITALIZA Y SE ENVIA A UNA UNIDAD DE PROCESAMIENTO DE IMAGENES (24) QUE CALCULA LAS PROPIEDADES OPTICAS DE LA LENTE. LA ABERTURA PUEDE CONSTAR DE UNA ABERTURA DE FORMA SIMPLE O ALTERNATIVAMENTE DE UNA PLURALIDAD DE ANILLOS CONCENTRICOS, ANULARES. PUEDEN EMPLEARSE LENTES DE CORRECCION (30, 32), TANTO DE FORMA PERMANENTE COMO SELECTIVA, PARA ALTERAR EL RAYO DE LUZ REFRACTADO ANTES DE QUE EL RAYO INTERSECTE LA SUPERFICIE DETECTORA.
