Abstract

"Disposición optoelectrónica de fotodetectores para la medición de longitud". Disposición optoelectrónica de fotodetectores en un aparato óptico de medición de longitud, incorporada en una aparato óptico de medición de longitud en donde son generadas franjas de luz de periodo p que se desplazan en una dirección X perpendicular a las franjas de luz, y que comprende dos fotodetectores (16,17 y 18,19) cada uno de dos fotodiodos (16-19) implantados sobre un plano de imagen (20), y un circuito electrónico para la generación de señales eléctricas para la medición sin distorsiones harmónicas, y sin que las desviaciones en el período (p) de la luz afecten al resultado de la medida, para lo cual se distribuyen los fotodiodos (16-19) sobre el plano de imagen (20) según una formación de áreas sensibles (16,17,18,19) de forma y tamaño determinadas (x, h) separadas unas de otras en serie en la dirección (X).
