  abstract = {Focusing is essential for the quality of thermal imaging. But due
	to physical constraints, only a small distance area around the focal
	distance, called the depth of field (DOF), appears acceptably sharp
	in a single thermogram. For scenes containing multiple objects at
	different distances from the camera or one along the optical axis
	outstretched object, it is hard to have all parts of the image sharp
	within one measurement. This is impossible if the distance between
	the closest and the farthest region is larger than the DOF. This
	work describes a solution to get an all-in-focus measurement that
	works by taking a measurement series with different focal settings
	and combining the sharp parts using digital image processing. Different
	possibilities for this process are discussed and examples are given.},
