Abstract

An exemplary apparatus and/or an exemplary method can be provided using which, it is possible (e.g., with at least one first arrangement) to measure an amplitude and/or a phase of at least one electromagnetic radiation provided from a particular portion of a sample. Further, it is possible (e.g., using at least one second arrangement) to scan a location of the particular portion along a path from a first point of the sample to a second point of the sample. In addition, it is possible to control the scan (e.g., with the second arrangement) such that the scan may comprise at least one first segment having a positive velocity and at least one segment having a negative velocity. A first distance of the first segment and/or the second segment can be smaller than a second distance between the first and second points.
