In certain examples, methods and apparatuses, such as circuits, are directed to scanning in a field of view (FoV) by using a pattern that improves sensing in a region of interest (RoI) within the FoV. In one example, a signal having multiple frequency components and a scan-pattern design are used, with a balanced or optimized set of attributes including a sampling density attribute, to scan a RoI in a FoV by sampling or traversing the RoI more times than other regions in the FoV. In more specific examples, circuitry finds the scan-pattern design based on an algorithm that processes different parameters involving at least one of amplitude and phase and processes a. number of different frequency components related to or including the multiple frequency components, wherein the number of different frequency components is from three to a threshold limit whereat processing different frequency components provides negligible improvement.
