1. A system comprising: a detector array comprising a plurality of pixels; a sweep device configured to move the detector array with respect to a scene; a system controller coupled to the detector array and the sweep device and configured to: present, on a display, a first set of mode selection input controls and a second set of waveband input controls, the first set of mode selection input controls comprising a first mode selection input control associated with a scan mode and a second mode selection input control associated with a stare mode, and the second set of waveband input controls comprising a plurality of waveband input controls, each waveband input control associated with a corresponding waveband of a plurality of different wavebands; determine an operating mode that comprises one of the scan mode and the stare mode based on a receipt of a user selection of either the first mode selection input control or the second mode selection input control; determine a first read-out pixel window comprising a first subset of pixels of the plurality of pixels of the detector array based on a receipt of a user selection of one of the plurality of waveband input controls, by: accessing a waveband mapping that maps each waveband of the plurality of different wavebands to a corresponding subset of pixels; and determining, based on the waveband mapping and the waveband that corresponds to the one of the plurality of waveband input controls, the first read-out pixel window; in the stare mode, generate, via the first read-out pixel window, a plurality of images of the scene at a first read-out framerate in the waveband that corresponds to the one of the plurality of waveband input controls; and in the scan mode: continuously move the detector array with respect to the scene; and read out the first read-out pixel window at a second read-out framerate that is a higher read-out framerate than the first read-out framerate to generate a plurality of images in the waveband that corresponds to the one of the plurality of waveband input controls.
