Abstract

Un sensor óptico de desplazamiento que comprende una fuente de radiación óptica (20), al menos una serie de detectores (22) de radiación, unos primer y segundo elementos (10, 12) cada uno de los cuales tiene unas primeras y segundas regiones (30, 32 ó 34, 36) alternadas, teniendo las primeras regiones (30, 34) y segundas regiones (32, 36) diferentes características ópticas, siendo cada uno de los primer y segundo elementos susceptible de ser desplazado de manera que las primeras y segundas regiones (30, 32 ó 34, 36) son expuestas a una radiación óptica procedente de la fuente (20) y pasan por la serie de detectores (22), caracterizado porque sobre la serie de detectores (22) se forma una imagen de dichas primeras y segundas regiones (30, 32 ó 34, 36) de los primer y segundo elementos (10, 12) y porque un procesador de datos (24) está conectado a la serie de detectores (22) para recibir de los mismos señales representando la intensidad de la radiación que incide en cada detector de la seriede detectores (22), operando dicho procesador de datos (24) para determinar las posiciones relativas de los primer y segundo elementos (10, 12) mediante la determinación de las posiciones relativas de unos bordes de la parte oscura de la imagen causada por las segundas regiones (32, 36) de los primer y segundo elementos (10, 12).
