Abstract: A spectral imager includes a filter array, a pixel array, and a lenslet array therebetween. The filter array includes a plurality of filter regions. The lenslet array includes a plurality of lenslets each configured to form a respective image of the filter array on a respective one of a plurality of regions of the pixel array. The spectral imager may also include a fore-optic lens, the filter array being located between the lenslet array and the fore-optic lens. The spectral imager may also include a fore-optic lens, the filter array being located between the lenslet array and the fore-optic lens. Each of the plurality of filter regions is configured to selectively transmit radiation based on wavelength and/or polarization.

Abstract: A birefringent filter includes an EM directing element in optical alignment with a first surface of the birefringent plate. A polarimetric imager includes a birefringent filter including a birefringent plate formed of a birefringent material and an EM directing element in optical alignment with a first surface of the birefringent plate. The imager further includes a detector in optical alignment with a second surface of the birefringent plate. A projection system includes an EM directing element and a birefringent filter. The filter includes (1) a birefringent plate formed of a birefringent material and having a first surface in optical alignment with the emissions source, and (2) an EM directing element in optical alignment with a second surface of the birefringent plate.
