Alignment of visible light sources based on thermal images

A method of operating a system, the method comprising:

• capturing an unblurred thermal image of a scene and an intentionally blurred image of the scene at a focal plane array (FPA) of an infrared imaging module;
• determining a plurality of non-uniform correction (NUC) terms based on the intentionally blurred thermal image;
• applying the NUC terms to the unblurred thermal image to remove noise form the unblurred thermal image;
• generating, from the unblurred thermal image, alignment guide information;
• receiving a force to selectively direct a visible light source to substantially align the visible light source with a desired subject based on the alignment guide information;
• and
• projecting a visible light beam from the visible light source substantially on the subject while the visible light source is aligned based on the alignment guide information.
