Abstract: Tunable filter arrays include an array of liquid crystal (LC) tunable Fabry-Perot (FP) microcavities. The microcavities are defined by first and second reflectors and an LC layer situated between the reflectors. The tunable filter is secured to an image sensor array so that the LC tunable microcavities are coupled to respective photodetectors of the image sensor array. Patterned electrodes are situated about the LC layer to tune the microcavities.
