The invention relates to a field stitching-based programmable polarization super spectrum imager, which comprises a front lens, a field diaphragm, a collimating lens, an acoustooptic tunable filter, an imaging lens, a detector and a detector control processing system, wherein the front lens, the field diaphragm, the collimating lens and the acoustooptic tunable filter are arranged in the same optical path in turn; an O-light optical path transition system is arranged in an O-light optical path after light in the O-light optical path is diffracted by the acoustooptic tunable filter; an E-lightoptical path transition system is arranged on an E-light optical path after light in the E-light optical path is diffracted by the acoustooptic tunable filter; and O light beams converted by the O-light optical path transition system and E light beams converted by the E-light optical path transition system pass through the imaging lens together, the photosensitive surface of the detector is positioned on the rear focal plane of the imaging lens, and the detector is connected with the detector control processing system. The invention provides a programmable polarization super spectrum imager synthesizing O light images and E light images on the photosensitive surface of the same detector through field stitching.
