Apparatus and methods for infrared resolution of closely-spaced objects
are disclosed. In one embodiment, a method of determining a set of
infrared amplitudes for a set of closely-spaced objects includes
receiving an unresolved infrared image of the set of closely-spaced
objects, and expressing the set of infrared amplitudes as a function of a
set of positions of the closely-spaced objects. The method further
includes formulating a set of simultaneous equations at least partially
based on the expression between the infrared amplitudes and the set of
positions of the closely-spaced objects, and solving the set of
simultaneous equations for the set of infrared amplitudes. In alternate
embodiments, the set of positions of the closely-spaced objects may be
provided by a non-infrared position sensor, or may be iteratively-derived
