Abstract

Un aparato para producir simultáneamente una pluralidad de imágenes separadas espacialmente, que comprende: un sistema óptico (1) dispuesto para producir una imagen asociada a una primera función óptica de transferencia; una rejilla de difracción (4) dispuesta para producir, en concierto con el sistema óptico, imágenes asociadas con cada orden de difracción; módulos ópticos auxiliares (5, 6, 7) que funcionan en órdenes de difracción individuales y medios para detectar las imágenes, en donde el sistema óptico (1) y la rejilla de difracción (4) están situados sobre un eje óptico, la rejilla de difracción (4) está situada en un plano de rejilla adecuado y los módulos ópticos auxiliares (5, 6, 7) modifican las funciones de transferencia óptica asociadas con las imágenes caracterizado porque el sistema óptico (1) y la rejilla de difracción (4) están dispuestos de forma tal que se hace imagen de múltiples planos objeto (9,10,11) y cada imagen asociada con un orden de difracción corresponde a un plano objeto diferente.
