| 1. A method for imaging an associated object, comprising the steps of:
directing one part of a low coherence optical radiation towards an associated object through an optical system, which ensures
focusing the low coherence optical radiation onto the object;
scanning the low coherence optical radiation being directed towards an associated object over a transverse scanning surface,
that is approximately orthogonal to the direction of propagation of said optical radiation;
providing a first lens component with positive focal power after the transverse scanning surface and providing a second lens
component with positive focal power after the first lens component, where the first lens component and the second lens component
are positioned to provide a constant propagation time for the low coherence optical radiation propagating from a given point
of the transverse scanning surface to a corresponding conjugate point of an image plane, thereby eliminating a transverse
scanning related aberration of an optical path length for the low coherence optical radiation directed towards an associated
object;
directing another part of the low coherence optical radiation along a reference optical path, and
combining an optical radiation having returned from an associated object with an optical radiation that passed through the
reference optical path;
visualizing an intensity of the optical radiation having returned from an associated object using for that an optical radiation
that is a result of the combining.
