An optical scanning probe comprises a handle to receive a light beam from a light guide a cannula, extending from a distal end of the handle a fiber, positioned partially inside the handle and partially inside the cannula, to guide the received light beam toward a distal end of the cannula a rotating scanner, rotatably positioned at least partially inside the cannula and configured to house a proximal portion of the fiber and a deflecting scanner, movably coupled to a distal end of the rotating scanner, configured to deflect a distal portion of the fiber, wherein the distal portion of the fiber is configured to emit and scan the guided light in a target region.
