    Abstract: A shutter includes micro-optics having first and second concentrator arrays. A transducer laterally displaces one of the first and second concentrator arrays between transmissive and shuttered modes. In the transmissive mode, the arrays of concentrators are optically aligned to permit electromagnetic energy passing through the first array of concentrators to pass through the second array of concentrators. In the shuttered mode, the electromagnetic radiation is blocked from passing through the second array of concentrators. The concentrators may be compound parabolic concentrators, or lenslets positioned on opposing plates with pinholes printed therethrough. The shutter may increase f-number of radiation passing therethrough, and may be used in a limited f-cone radiation source with shuttering abilities, for example reducing f-cone of radiation output from the radiation source.

    Abstract translation: 快门包括具有第一和第二集中器阵列的微光学器件。 换能器在透射和快门模式之间横向移位第一和第二聚光器阵列中的一个。 在透射模式中,聚光器阵列被光学对准以允许通过第一集中器阵列的电磁能量穿过第二阵列的聚光器。 在快门模式中,电磁辐射被阻止通过第二阵列的聚光器。 集中器可以是复合抛物面聚光器,或者位于相对的板上的小透镜,其中针孔印刷在其中。 快门可以增加通过其中的f数量的辐射,并且可以用于具有快门能力的有限的f-锥体辐射源,例如减小从辐射源输出的辐射的f锥。
