1. An infrared imaging system comprising:
a plurality of detector arrays defining a conjugate image plane;
a data-processing unit comprising a processor and configured to:
acquire, from the plurality of detector arrays, a plurality of defocused images of at least one reference source displaced away from the conjugate image plane, and
dynamically calibrate the plurality of detector arrays to reduce a difference in temperature estimates of the at least one reference source based on the plurality of defocused images.
