La distancia que media entre el centro del sistema óptico y el foco se llama distancia focal, y el plano perpendicular al eje óptico que pasa por el foco es el plano focal. Así, en un aparato fotográfico, el plano focal es representado por la emulsión sensible y la distancia focal es la que media entre ella y el objetivo. 1, record 1, Spanish, - foco

Pour répondre à cette interrogation, un concept d'expérience original a été imaginé : deux impulsions laser ultrabrèves de longueurs d'onde différentes mais dont la somme de fréquence est suffisante pour exciter la fluorescence d'un colorant dilué dans la microcavité sont décalées temporellement (expérience pompe-sonde). La fluorescence n'est excitée que lorsque les deux paquets d'onde se recouvrent spatialement : on réalise ainsi un corrélateur optique. 3, record 2, French, - corr%C3%A9lateur%20optique

Hace más de 30 años Van der Lugt inició una época de expansión de la óptica de Fourier al introducir por primera vez una exitosa configuración para el procesado óptico de datos-el llamado correlador óptico. Esta operación está basada en la capacidad de una lente convexa de realizar una operación proporcional a la transformada de Fourier en dos dimensiones de un objeto y cuya respuesta está localizada en el plano focal. 1, record 2, Spanish, - correlador%20%C3%B3ptico
