Abstract

Una máscara para uso en sensado compresivo de radiación entrante, la máscara que comprende: un cuerpo formado de un material que modula una intensidad de radiación entrante de interés. El cuerpo tiene una pluralidad de regiones de apertura de máscara, cada una que comprende al menos una apertura de máscara que permite una mayor transmisión de la radiación con respecto a otras porciones de la región de apertura de máscara respectiva, la transmisión relativa que es suficiente para permitir reconstrucción de las mediciones de sensado compresivo; la máscara tiene uno o más ejes de simetría rotacional con respecto a las regiones de apertura de máscara; las aperturas de máscara tienen una forma que proporciona simetría después de una rotación alrededor del uno o más ejes de simetría rotacional; y es menor que uno la coherencia mutua de una matriz de sensado generada por la rotación de las regiones de apertura de máscara respectivas. También se proporciona un sistema formador de imágenes para sensado compresivo de radiación entrante que comprende esta máscara.
