The present invention provides a system for imaging an object comprising: an optical imaging unit for imaging an object on a detection array, the optical imaging unit defining an optical axis and comprising a multicore fiber configured to collect light from the object at an input edge of the multicore fiber and transfer collected light to an output edge of the multicore fiber； a displacing unit configured to shift the input edge of the multicore fiber relatively to the object in a plane substantially perpendicular to the optical axis to obtain a set of shifted images of the object； and an operating unit configured to operate the displacing unit by setting a shifting amplitude to either a first amplitude inferior or equal to the diameter of a core of the multicore fiber or a second amplitude superior or equal to the diameter of the multicore fiber.
