Abstract: A dynamically controllable polarizer integrated with an imaging detector to provide “on demand” variable polarization measurements. In one example, an imaging system includes a detector array including a plurality of pixels arranged in a two-dimensional array, and a dynamic polarizer coupled to the detector array, the dynamic polarizer including at least one patterned layer of a material disposed on the detector array, the material being operable to alter its conductivity responsive to an applied stimulus to reversibly transition between a polarizing state and a non-polarizing state.

Abstract: Multi-spectral filter elements and methods of formation are disclosed. Each multi-spectral filter element may include a plurality of sub-filters that are, in some examples, each adapted to respond to electromagnetic radiation within respective ones of a plurality of spectral bands. A method example includes forming an optical cavity layer. Volume of the optical cavity layer can be reduced in at least N−1 number of spatial regions. The reducing may include a number of selective removal steps equal to the binary logarithm function Log2N. In this example, each spatial region corresponds to a respective one of the plurality sub-filters. The plurality of sub-filters includes at least N sub-filters. In particular examples, the respective ones of the plurality of spectral bands may be at least partially discrete with respect to each other.
