More Information
Summary:Mechanisms for identifying energy received from a scene are provided. A coded aperture in an optical system receives energy from a scene. The coded aperture comprises a plurality of wavelength filter sets arranged in a predetermined pattern. Each wavelength filter set is configured to transmit energy in a corresponding wavelength band of a plurality of different wavelength bands. The coded aperture transmits the energy toward a detector array comprising a plurality of detector elements. The detector array generates sensor data that quantifies energy received by each detector element. The sensor data is processed based on the predetermined pattern to identify spatial locations of energy in each corresponding wavelength band with respect to the scene.
