1. A method, comprising: for each frame period of a plurality of frame periods of a detector array comprising a plurality of pixels: rotating a pixel mask with respect to the detector array based on a rotational movement of a scene with respect to the detector array to identify a subset of pixels of the detector array; integrating, by the pixels in the subset of pixels, energy from the scene; and reading out the pixels in the subset of pixels to generate a pixel data set; generating an image portion of the scene based on the pixel data set; and combining successive image portions to form an image of the scene.
