OPTICAL ELEMENT INCLUDING MICROLENS ARRAY

An optical element including an array of microlenses, a pinhole mask, and a wavelength selective filter is described. The pinhole mask includes an array of pinholes with each pinhole in the array of pinholes aligned with a microlens in the first array of microlenses. The wavelength selective filter is adapted to transmit a first light ray having a first wavelength and transmitted from a first microlens in the array of microlenses through a first pinhole in the array of pinholes aligned with the first microlens, and to attenuate a second light ray having the first wavelength and transmitted from the first microlens through a second pinhole in the array of pinholes aligned with a second microlens in the first array of microlenses adjacent to the first microlens. 本发明描述了一种光学元件，所述光学元件包括微透镜阵列、针孔掩模和波长选择性滤光器。所述针孔掩模包括针孔阵列，其中所述针孔阵列中的每个针孔与所述第一微透镜阵列中的微透镜对准。所述波长选择性滤光器适于透射具有第一波长并且从所述微透镜阵列中的第一微透镜透射穿过所述针孔阵列中与所述第一微透镜对准的第一针孔的第一光线，并且减弱具有所述第一波长并且从所述第一微透镜透射穿过所述针孔阵列中的第二针孔的第二光纤，所述第二针孔与所述第一微透镜阵列中邻近所述第一微透镜的第二微透镜对准。
